SAFETY AND GENERAL INFORMATION
Information and Instructions on RF Energy Exposure and Product Safety
READ THIS IMPORTANT INFORMATION ON SAFE AND EFFICIENT OPERATION BEFORE
USING YOUR MOTOROLA HANDHELD PORTABLE TWO-WAY RADIO
The information provided in this document supersedes the general safety information contained in user guides
published prior to June 2001. For information regarding radio use in a hazardous atmosphere please refer to the
Factory Mutual (FM) Approval Product Listing Manual or Instruction Card, which is included with radio models
that offer this capability.
Compliance with RF Energy Exposure Standards
Your Motorola two-way radio is designed and tested to comply with a number of national and international
standards and guidelines (listed below) regarding human exposure to radio frequency electromagnetic energy.
This radio complies with the IEEE (FCC) and ICNIRP exposure limits for occupational/controlled RF exposure
environment at duty cycles of up to 50% talk-50% listen and should be used for occupational use only. In terms of
measuring RF energy for compliance with the FCC exposure guidelines, your radio radiates measurable RF
energy only while it is transmitting (during talking), not when it is receiving (listening) or in standby mode. Note
that the approved, supplied batteries for this radio are rated for a 5-5-90 duty cycle (5% talk - 5% listen - 90%
standby), even though this radio complies with the FCC occupational exposure limits at duty cycles of up to 50%
talk.
Your Motorola two-way radio complies with the following RF energy exposure standards and guidelines:
•
•
•
•
•
•
•
United States Federal Communications Commission, Code of Federal Regulations; 47CFR part
2 sub-part J
American National Standards Institute (ANSI) / Institute of Electrical and Electronic Engineers
(IEEE) C95. 1-1992
Institute of Electrical and Electronic Engineers (IEEE) C95.1-1999 Edition
International Commission on Non-Ionizing Radiation Protection (ICNIRP) 1998
Ministry of Health (Canada) Safety Code 6. Limits of Human Exposure to Radio frequency Electromagnetic Fields in the Frequency Range from 3 kHz to 300 GHz, 1999
Australian Communications Authority Radiocommunications (Electromagnetic Radiation Human Exposure) Standard 2001
ANATEL, Brazil Regulatory Authority, Resolution 256 (April 11, 2001) “additional requirements
for SMR, cellular and PCS product certification.”
Operational Instructions and Training Guidelines
To ensure optimal performance and compliance with the occupational/controlled environment RF energy
exposure limits in the above standards and guidelines, users should transmit no more than 50% of the time and
always adhere to the following procedures:
Transmit and Receive
To transmit (talk), push the Push-To-Talk (PTT) button; to receive, release the PTT button.
Hand-held Radio Operation
Hold the radio in a vertical position with the microphone one to two
inches (2.5 to 5 cm) away from the lips.
2.5 to 5.0 cm
(1 to 2 in.)
Body-worn Operation
Always place the radio in a Motorola approved clip, holder, holster, case,
or body harness for this product. Use of non-Motorola-approved
accessories may exceed FCC RF exposure guidelines.
If you do not use a Motorola approved body-worn accessory and are not
using the radio in the intended use position in front of the face, then ensure the antenna and the radio are kept
2.5 cm (one inch) from the body when transmitting.
ii
Antennas & Batteries
Use only Motorola approved supplied antenna or Motorola approved replacement antenna.
Unauthorized antennas, modifications, or attachments could damage the radio and may violate FCC regulations.
Use only Motorola approved supplied batteries or Motorola approved replacement batteries.
Use of non-Motorola-approved antennas or batteries may exceed FCC RF exposure guidelines.
Approved Accessories
For a list of approved Motorola accessories please contact your dealer, or local Motorola representative.
ELECTROMAGNETIC INTERFERENCE/COMPATIBILITY
NOTE Nearly every electronic device is susceptible to electromagnetic interference (EMI) if inadequately
shielded, designed, or otherwise configured for electromagnetic compatibility.
Facilities
To avoid electromagnetic interference and/or compatibility conflicts, turn off your radio in any facility where
posted notices instruct you to do so. Hospitals or health care facilities may be using equipment that is sensitive to
external RF energy.
Aircraft
When instructed to do so, turn off your radio when on board an aircraft. Any use of a radio must be in accordance
with applicable regulations per airline crew instructions.
Medical Devices
•
Pacemakers
The Advanced Medical Technology Association (AdvaMed) recommends that a minimum separation of 6 inches
(15 centimeters) be maintained between a handheld wireless radio and a pacemaker. These recommendations
are consistent with those of the U.S. Food and Drug Administration.
Persons with pacemakers should:
•
•
•
•
•
ALWAYS keep the radio more than 6 inches (15 centimeters) from their pacemaker when the
radio is turned ON.
not carry the radio in the breast pocket.
use the ear opposite the pacemaker to minimize the potential for interference.
turn the radio OFF immediately if you have any reason to suspect that interference is taking
place.
Hearing Aids
Some digital wireless radios may interfere with some hearing aids. In the event of such interference, you may
want to consult your hearing aid manufacturer to discuss alternatives.
•
Other Medical Devices
If you use any other personal medical device, consult the manufacturer of your device to determine if it is
adequately shielded from RF energy. Your physician may be able to assist you in obtaining this information.
Driver Safety
Check the laws and regulations on the use of radios in the area where you drive. Always obey them.
When using your radio while driving, please:
•
•
•
Give full attention to driving and to the road.
Use hands-free operation, if available.
Pull off the road and park before making or answering a call if driving conditions so require.
iii
OPERATIONAL WARNINGS
For Vehicles With an Air Bag
Do not place a portable radio in the area over an air bag or in the air bag deployment area. Air
bags inflate with great force. If a portable radio is placed in the air bag deployment area and the
air bag inflates, the radio may be propelled with great force and cause serious injury to
occupants of the vehicle.
!
WARNING
Potentially Explosive Atmospheres
Turn off your radio prior to entering any area with a potentially explosive atmosphere, unless it is a radio type
especially qualified for use in such areas as “Intrinsically Safe” (for example, Factory Mutual, CSA, UL, or
CENELEC). Do not remove, install, or charge batteries in such areas. Sparks in a potentially explosive
atmosphere can cause an explosion or fire resulting in bodily injury or even death.
NOTE The areas with potentially explosive atmospheres referred to above include fueling areas
such as below decks on boats, fuel or chemical transfer or storage facilities, and areas
where the air contains chemicals or particles, such as grain, dust or metal powders. Areas
with potentially explosive atmospheres are often but not always posted.
Blasting Caps and Areas
To avoid possible interference with blasting operations, turn off your radio when you are near electrical blasting
caps, in a blasting area, or in areas posted: “Turn off two-way radio.” Obey all signs and instructions.
OPERATIONAL CAUTIONS
Antennas
Do not use any portable radio that has a damaged antenna. If a damaged antenna comes into
contact with your skin, a minor burn can result.
!
Caution
Batteries
All batteries can cause property damage and/or bodily injury such as burns if a conductive material such as
jewelry, keys, or beaded chains touch exposed terminals. The conductive material may complete an electrical
circuit (short circuit) and become quite hot. Exercise care in handling any charged battery, particularly when
placing it inside a pocket, purse, or other container with metal objects.

POWER UP SELF-TEST
1.0
Error Codes
Turning on the radio using the on/off volume control starts a self-test routine which checks the RAM,
ROM checksum, EEPROM hardware and EEPROM checksum. If these checks are successfully
completed, the radio will generate the Self-Test Pass Tone. If the self-test is not successful, a “bonk”
is heard. Radios with displays are able to display these error messages:
•
•
•
•
“RAM TST ERROR” for <RAM Test Error>
“ROM CS ERROR” for <ROM Checksum Error>
“EEPRM HW ERROR” for <EEPROM Hardware Test Error>
“EEPRM CS ERROR” for <EEPROM Checksum Error>
NOTE Radio without display emits only “bonk” (300 Hz) tone if it fails the self-test.
Error Code
Explanation
Corrective Action
“RAM TST ERROR”
RAM Test Failure
Retest radio by turning it off and turning it on again. If
message reoccurs, replace RAM (U405).
“ROM CS ERROR”
ROM Checksum is
wrong.
Reprogram FLASH Memory, then retest. If message
reoccurs, replace ROM (U406).
“EEPRM HW ERROR”
Codeplug structure
mismatch, non
existence of
codeplug.
Reprogram codeplug with correct version and retest
radio. If message reoccurs, replace EEPROM
(U407).
“EEPRM CS ERROR”
Codeplug checksum is wrong.
Reprogram codeplug.
No Display
Display module is
not connected
properly.
Display module is
damaged.
Check connection between main board and display
module.
Replace with new display module.

Figure 4-1: DC Power Distribution Block Diagram
Figure 4-1 illustrates the DC distribution throughout the radio board. A 7.5V battery (BATT 7.5V)
supplies power directly to the electronic on/off control as UNSWB+. When the radio is turned on,
MECH_SWB+ (on/off/volume control) will trigger the electronic on/off control(momentary-on path),
then SWB+ is distributed as shown in Figure 4-1. Vdda from 3.3V Vdda regulator will then supply the
microprocessor. Data is then sent to ASFIC_CMP to turn on GCB4(DAC). GCB4 will take over the
momentary-on path within 12ms. SWB+ will continue to support the whole board until the radio is
turned off.
Radio will be turned-off on two conditions;
1. MECH_SWB+ turned off
2. Low battery
4-2
Controller Board
When low battery level is detected by the microprocessor through both conditions above, it will store
the radio personality data to EEPROM before turning off.

Controller Board
3.1
General
The controller board is the central interface between the various subsytems of the radio. It is
separated into digital and audio architectures. The digital portion consists of a special Motorola
microcontroller (HC11FL0). The audio power amplifier (Audio PA) and audio/signalling/filter/
companding IC (ASFIC_CMP) form the backbone of the audio/signalling architecture.

MCU configuration
There is one common MCU architecture for low-tier as well as for the high-tier products. It covers the
Conventional and Trunking portables. An open architecture system with the new HC11FL0 as the
processor is used. Combinations of different size RAM, ROM and EEPROM are available for various
application software.
REAL TIME CLOCK (RTC)
This radio supports Real Time Clock (RTC) module for purposes of Message Time Stamping and
Time Keeping. The RTC module resides in the micro-processor HC11FL0. It is kept alive by a backup Lithium Ion battery when the primary battery is removed.

Circuit Description
The RTC module which resides in the HC11FL0 is powered by the ModB/Vstby pin and PI6/PI7 form
the crystal oscillator circuit. Clock frequency of 38.4kHz from a crystal oscillator provides the
reference signal. In the processor, the frequency is divided down to 1Hz.
As the RTC module is powered separately from the processor Vdd, the RTC is kept alive through the
ModB / Vstby pin when the radio is switched off. A small button Lithium Ion battery continues to feed
the RTC when the primary battery is removed.
A MOSFET Q416 switches in the LiO supply when Vdd is removed. Q416 also provides isolation from
BOOT_CTRL function in the event of radio program flashing. A small 3.3V regulator is used to charge
the LiO battery.

KEYPAD BOARD INFORMATION
Theory of Operation
Keypad
The LED_EN setting is set by the codeplug. When the value is set to high, the LED will not light up
during power up and vice versa.
U602 is a comparator that will compare the voltage when any one of the keypad row or keypad
column keys is being pressed. Therefore when a key is being pressed, it will send a message to the
microprocessor through the output (KEY_INT) telling it that a key has been pressed. The
microprocessor will then sample the Analog to Digital voltages at the keypad row and keypad column
and map it with the table so that the key being pressed can be identified. Once the key has been
identified, the message that corresponds to the key will show up at the display.

3.1
General
(Refer to Figure 6-1)
The UHF transmitter contains five basic circuits:
1. power amplifier
2. antenna switch
3. harmonic filter
4. antenna matching network
5. power control integrated circuit (PCIC).
3.1.1 Power Amplifier
The power amplifier consists of two devices:
1. 9Z67 LDMOS driver IC (U101) and
2. PRF1507 LDMOS PA (Q110).
The 9Z67 LDMOS driver IC contains a 2 stage amplification with a supply voltage of 7.3V.
This RF power amplifier is capable of supplying an output power of 0.3W (pin 6 and 7) with an input
signal of 2mW (3dBm) (pin16). The current drain would typically be 160mA while operating in the
frequency range of 403-470MHz.
The PRF1507 LDMOS PA is capable of supplying an output power of 7W with an input signal of
0.3W. The current drain would typically be 1300mA while operating in the frequency range of 403470MHz. The power output can be varied by changing the biasing voltage.
Transmitter
6A-5
3.1.2 Antenna Switch
The antenna switch circuit consists of two PIN diodes (CR101 and CR102), a pi network (C107, L104
and C106), and two current limiting resistors (R101, R170). In the transmit mode, B+ at PCIC (U102)
pin 23 will go low and turn on Q111 where a B+ bias is applied to the antenna switch circuit to bias the
diodes "on". The shunt diode (CR102) shorts out the receiver port, and the pi network, which
operates as a quarter wave transmission line, transforms the low impedance of the shunt diode to a
high impedance at the input of the harmonic filter. In the receive mode, the diodes are both off, and
hence, there exists a low attenuation path between the antenna and receiver ports.
3.1.3 Harmonic Filter
The harmonic filter consists of C104, L102, C103, L101 and C102. The design of the harmonic filter
for UHF is that of a modified Zolotarev design. It has been optimized for efficiency of the power
module. This type of filter has the advantage that it can give a greater attenuation in the stop-band for
a given ripple level. The harmonic filter insertion loss is typically less than 1.2dB.
3.1.4 Antenna Matching Network
A matching network which is made up of L116 is used to match the antenna's impedance to the
harmonic filter. This will optimize the performance of the transmitter and receiver into an antenna.
3.1.5 Power Control Integrated Circuit (PCIC)
The transmitter uses the Power Control IC (PCIC), U102 to regulate the power output of the radio.
The current to the final stage of the power module is supplied through R101, which provides a voltage
proportional to the current drain. This voltage is then fedback to the Automatic Level Control (ALC)
within the PCIC to regulate the output power of the transmitter.
The PCIC has internal digital to analog converters (DACs) which provide the reference voltage of the
control loop. The reference voltage level is programmable through the SPI line of the PCIC.
There are resistors and integrators within the PCIC, and external capacitors (C133, C134 and C135)
in controlling the transmitter rising and falling time. These are necessary in reducing the power
splatter into adjacent channels.
CR105 and its associated components are part of the temperature cut back circuitry. It senses the
printed circuit board temperature around the transmitter circuits and output a DC voltage to the PCIC.
If the DC voltage produced exceeds the set threshold in the PCIC, the transmitter output power will be
reduced so as to reduce the transmitter temperature.

Receiver Front-End
(Refer to UHF Receiver Front End Schematic Diagram on page 6A-18 and UHF Transmitter
Schematic Diagram on page 6A-22)
The RF signal is received by the antenna and applied to a low-pass filter. For UHF, the filter consists
of L101, L102, C102, C103, C104. The filtered RF signal is passed through the antenna switch. The
antenna switch circuit consists of two PIN diodes(CR101 and CR102) and a pi network (C106, L104
and C107).The signal is then applied to a varactor tuned bandpass filter. The UHF bandpass filter
comprises of L301, L302, C302, C303, C304, CR301 and CR302. The bandpass filter is tuned by
applying a control voltage to the varactor diodes(CR301 and CR302) in the filter.
The bandpass filter is electronically tuned by the DACRx from IC404 which is controlled by the
microprocessor. Depending on the carrier frequency, the DACRx will supply the tuned voltage to the
varactor diodes in the filter. Wideband operation of the filter is achieved by shifting the bandpass filter
across the band.
The output of the bandpass filter is coupled to the RF amplifier transistor Q301 via C307. After being
amplified by the RF amplifier, the RF signal is further filtered by a second varactor tuned bandpass
filter, consisting of L306, L307, C313, C317, CR304 and CR305.
Both the pre and post-RF amplifier varactor tuned filters have similar responses. The 3 dB bandwidth
of the filter is about 50 MHz. This enables the filters to be electronically controlled by using a single
control voltage which is DACRx .
Receiver
6A-7
The output of the post-RF amplifier filter which is connected to the passive double balanced mixer
consists of T301, T302 and CR306. Matching of the filter to the mixer is provided by C381. After
mixing with the first LO signal from the voltage controlled oscillator (VCO) using low side injection, the
RF signal is down-converted to the 45.1 MHz IF signal.
The IF signal coming out of the mixer is transfered to the crystal filter (FL301) through a resistor pad
and a diplexer (C322 and L310). Matching to the input of the crystal filter is provided by C324 and
L311. The crystal filter provides the necessary selectivity and intermodulation protection.
4.2
Receiver Back-End
(Refer to UHF Receiver Back End Schematic Diagram on page 6A-19)
The output of crystal filter FL301 is matched to the input of IF amplifier transistor Q302 by
components R352 and C325. Voltage supply to the IF amplifier is taken from the receive 5 volts (R5).
The IF amplifer provides a gain of about 7dB. The amplified IF signal is then coupled into U301(pin 3)
via C330, C338 and L330 which provides the matching for the IF amplifier and U301.
The IF signal applied to pin 3 of U301 is amplified, down-converted, filtered, and demodulated, to
produce the recovered audio at pin 27 of U301. This IF IC is electronically programmable, and the
amount of filtering (which is dependent on the radio channel spacing) is controlled by the
microprocessor. Additional filtering, once externally provided by the conventional ceramic filters, is
replaced by internal filters in the IF module (U301).
The IF IC uses a type of direct conversion process, whereby the externally generated second LO
frequency is divided by two in U301 so that it is very close to the first IF frequency. The IF IC (U301)
synthesizes the second LO and phase-locks the VCO to track the first IF frequency. The second LO
is designed to oscillate at twice the first IF frequency because of the divide-by-two function in the IF
IC.
In the absence of an IF signal, the VCO will “search” for a frequency, or its frequency will vary close to
twice the IF frequency. When an IF signal is received, the VCO will lock onto the IF signal. The
second LO/VCO is a Colpitts oscillator built around transistor Q320. The VCO has a varactor diode,
CR310, to adjust the VCO frequency. The control signal for the varactor is derived from a loop filter
consisting of C362, C363, C364, R320 and R321.
The IF IC (U301) also performs several other functions. It provides a received signal-strength
indicator (RSSI) and a squelch output. The RSSI is a dc voltage monitored by the microprocessor,
and used as a peak indicator during the bench tuning of the receiver front-end varactor filter. The
RSSI voltage is also used to control the automatic gain control (AGC) circuit at the front-end.
The demodulated signal on pin 27 of U301 is also used for squelch control. The signal is routed to
U404 (ASFIC) where squelch signal shaping and detection takes place. The demodulated audio
signal is also routed to U404 for processing before going to the audio amplifier for amplification.
6A-8
4.3
Receiver
Automatic Gain Control Circuit
(Refer to UHF Receiver Front End Schematic Diagram on page 6A-18)
The front end automatic gain control circuit is to provide automatic gain reduction of the front end RF
amplifier via feedback. This action is necessary to prevent overloading of backend circuits. This is
achieved by drawing some of the output power from the RF amplifier’s output. At high radio
frequencies, capacitor C331 provides the low impedance path to ground for this purpose. CR308 is a
PIN diode used for switching the path on or off. A certain amount of forward biasing current is needed
to turn the PIN diode on. Transistors Q315 provides this current where upon saturation, current will
flow via R347, PIN diode, collector and emitter of Q315 and R319 before going to ground. Q315 is an
NPN transistor used for switching here. Maximum current flowing through the PIN is mainly limited by
the resistor R319.
Radio signal strength indicator, RSSI, a voltage signal, is used to drive Q315 to saturation hence
turning it on. RSSI is produced by U301 and is proportional to the gain of the RF amplifier and the
input RF signal power to the radio.
Resistor network at the input to the base of Q315 is scaled to turn on Q315, hence activating the
AGC, at certain RSSI levels. In order to turn on Q315, the voltage across the transistor’s base to
ground must be greater or equal to the voltage across R319, plus the base-emitter voltage (Vbe)
present at Q315. The resistor network with thermistor RT300 is capable of providing temperature
compensation to the AGC circuit, as RSSI generated by U301 is lower at cold temperatures
compared to normal operation at room temperature. Resistor R300 and capacitor C397 form an R-C
network used to dampen any transient instability while the AGC is turning on.

Figure 6-3: Frequency Generation Unit Block Diagram
The Frequency Generation Circuitry is composed of two main ICs, the Fractional-N synthesizer
(U201), and the VCO/Buffer IC (U241). Designed in conjunction to maximize compatibility, the two
ICs provide many of the functions that normally would require additional circuitry. The synthesizer
block diagram illustrates the interconnect and support circuitry used in the region. Refer to the
relevant schematics for the reference designators.
The synthesizer is powered by regulated 5V and 3.3V which come from U247 and U248 respectively.
The synthesizer in turn generates a superfiltered 4.5V which powers U241.
In addition to the VCO, the synthesizer must interface with the logic and ASFIC circuitry.
Programming for the synthesizer is accomplished through the data , clock and chip select lines from
the microprocessor. A 3.3V dc signal from synthesizer lock detect line indicates to the microprocessor
that the synthesizer is locked.
Transmit modulation from the ASFIC is supplied to pin10 of U201. Internally the audio is digitized by
the Fractional-N and applied to the loop divider to provide the low-port modulation. The audio runs
through an internal attenuator for modulation balancing purposes before going out to the VCO.

Frequency Generation Circuitry
Synthesizer
(Refer to UHF Synthesizer Schematic Diagram on page 6A-20)
The Fractional-N Synthesizer uses a 16.8MHz crystal (FL201) to provide a reference for the system.
The LVFractN IC (U201) further divides this to 2.1MHz, 2.225MHz, and 2.4MHz as reference
frequencies. Together with C206, C207, C208, R204 and CR203 , they build up the reference
oscillator which is capable of 2.5ppm stability over temperatures of -30 to 85°C. It also provides
16.8MHz at pin 19 of U201 to be used by ASFIC and LVZIF.
The loop filter which consist of C231, C232, C233, R231, R232 and R233 provides the necessary dc
steering voltage for the VCO and determines the amount of noise and spur passing through .
In achieving fast locking for the synthesizer, an internal adapt charge pump provides higher current at
pin 45 of U201 to put synthesizer within the lock range. The required frequency is then locked by
normal mode charge pump at pin 43 .
Both the normal and adapt charge pumps get their supply from the capacitive voltage multiplier which
is made up of C258, C259, C228, triple diode CR201 and level shifters U210 and U211. Two 3.3V
square waves ( 180 deg out of phase) are first shifted to 5V, then along with regulated 5V , put
through arrays of diodes and capacitors to build up 13.3V at pin 47 of U201.

The VCOBIC (U241) in conjunction with the Fractional-N synthesizer (U201) generates RF in both
the receive and the transmit modes of operation. The TRB line (U241 pin 19) determines which
oscillator and buffer will be enabled. A sample of the RF signal from the enabled oscillator is routed
from U241 pin 12, through a low pass filter, to the prescaler input (U201 pin 32). After frequency
comparison in the synthesizer, a resultant CONTROL VOLTAGE is received at the VCO. This voltage
is a DC voltage between 3.5V and 9.5V when the PLL is locked on frequency.
6A-12
Frequency Generation Circuitry
The VCOBIC(U241) is operated at 4.54 V (VSF) and Fractional-N synthesizer (U201) at 3.3V. This
difference in operating voltage requires a level shifter consisting of Q260 and Q261 on the TRB line.
The operation logic is shown in Table 6-1.

In the receive mode, U241 pin 19 is low or grounded. This activates the receive VCO by enabling the
receive oscillator and the receive buffer of U241. The RF signal at U241 pin 8 is run through a
matching network. The resulting RF signal is the LO RF INJECTION and it is applied to the mixer at
T302 (refer to UHF Receiver Front End Schematic Diagram on page 6A-18).
During the transmit condition, when PTT is depressed, five volts is applied to U241 pin 19. This
activates the transmit VCO by enabling the transmit oscillator and the transmit buffer of U241. The RF
signal at U241 pin 10 is injected into the input of the PA module (U101 pin16). This RF signal is the
TX RF INJECTION. Also in transmit mode, the audio signal to be frequency modulated onto the
carrier is received through the U201 pin 41.
When a high impedance is applied to U241 pin19, the VCO is operating in BATTERY SAVER mode.
In this case, both the receive and transmit oscillators as well as the receive transmit and prescaler
buffer are turned off.

General
(Refer to Figure 6-1)
The VHF transmitter contains five basic circuits:
1. power amplifier
2. antenna switch
3. harmonic filter
4. antenna matching network
5. power control integrated circuit (PCIC).
3.1.1 Power Amplifier
The power amplifier consists of two devices:
1. 9Z67 LDMOS driver IC (U3501) and
2. PRF1507 LDMOS PA (Q3501).
The 9Z67 LDMOS driver IC contains a 2 stage amplification with a supply voltage of 7.3V.
This RF power amplifier is capable of supplying an output power of 0.3W (pin 6 and 7) with an input
signal of 2mW (3dBm) (pin16). The current drain would typically be 130mA while operating in the
frequency range of 136-174MHz.
The PRF1507 LDMOS PA is capable of supplying an output power of 7W with an input signal of 0.3W.
The current drain would typically be 1800mA while operating in the frequency range of 136-174MHz.
The power output can be varied by changing the biasing voltage.
Transmitter
6B-5
3.1.2 Antenna Switch
The antenna switch circuit consists of two PIN diodes (D3521 and D3551), a pi network (C3531,
L3551 and C3550), and three current limiting resistors (R3571, R3572, R3573 ). In the transmit
mode, B+ at PCIC (U3502) pin 23 will go low and turn on Q3561 where a B+ bias is applied to the
antenna switch circuit to bias the diodes "on". The shunt diode (D3551) shorts out the receiver port,
and the pi network, which operates as a quarter wave transmission line, transforms the low
impedance of the shunt diode to a high impedance at the input of the harmonic filter. In the receive
mode, the diodes are both off, and hence, there exists a low attenuation path between the antenna
and receiver ports.
3.1.3 Harmonic Filter
The harmonic filter consists of C3532 to C3536, L3531 and L3532. This network forms a low-pass
filter to attenuate harmonic energy of the transmitter to specifications level. The harmonic filter
insertion loss should be less than 1.2dB.
3.1.4 Antenna Matching Network
A matching network which is made up of L3538 and C3537 is used to match the antenna's
impedance to the harmonic filter. This will optimize the performance of the transmitter and receiver
into an antenna.
3.1.5 Power Control Integrated Circuit (PCIC)
The transmitter uses the Power Control IC (PCIC), U3502 to control the power output of the radio by
maintaining the radio current drain. The current to the final stage of the power module is supplied
through R3519 (0.1ohms), which provides a voltage proportional to the current drain. This voltage is
then fedback to the Automatic Level Control (ALC) within the PCIC to keep the whole loop stable.
The PCIC has internal digital to analog converters (DACs) which provide the reference voltage of the
control loop. The voltage level is controlled by the microprocessor through the data line of the PCIC.
There are resistors and integrators within the PCIC, and external capacitors (C3562, C3563 and
C3565) in controlling the transmitter rising and falling time. These are necessary in reducing the
power splatter into adjacent channels.
U3503 and its associated circuitry acts as a temperature cut back circuitry. This circuitry provides the
necessary voltage to the PCIC to cut the transmitter power when the radio temperature gets too high.

Receiver Front-End
(Refer toVHF Receiver Front End Schematic Diagram on page 6B-20, VHF Receiver Back End
Schematic Diagram on page 6B-21, and VHF Transmitter Schematic Diagram on page 6B-24)
The RF signal is received by the antenna and applied to a low-pass filter. For VHF, the filter consists
of L3531, L3532, C3532 to C3563. The filtered RF signal is passed through the antenna switch. The
antenna switch circuit consists of two PIN diodes(D3521 and D3551) and a pi network (C3531, L3551
and C3550).The signal is then applied to a varactor tuned bandpass filter. The VHF bandpass filter
comprises of L3301, L3303, C3301 to C3304 and D3301. The bandpass filter is tuned by applying a
control voltage to the varactor diode (D3301) in the filter.
The bandpass filter is electronically tuned by the DACRx from IC404 which is controlled by the
microprocessor. Depending on the carrier frequency, the DACRx will supply the tuned voltage to the
varactor diodes in the filter. Wideband operation of the filter is achieved by shifting the bandpass filter
across the band.
The output of the bandpass filter is coupled to the RF amplifier transistor Q3302 via C3306. After
being amplified by the RF amplifier, the RF signal is further filtered by a second varactor tuned
bandpass filter, consisting of L3305, L3306, C3311 to C3314 and D3302.
Both the pre and post-RF amplifier varactor tuned filters have similar responses. The 3 dB bandwidth
of the filter is about 12 MHz. This enables the filters to be electronically controlled by using a single
control voltage which is DACRx .
Receiver
6B-7
The output of the post-RF amplifier filter is connected to the passive double balanced mixer which
consists of T3301, T3302 and CR3301. Matching of the filter to the mixer is provided by C3317,
C3318 and L3308. After mixing with the first LO signal from the voltage controlled oscillator (VCO)
using high side injection, the RF signal is down-converted to the 45.1 MHz IF signal.
The IF signal coming out of the mixer is transfered to the crystal filter (Y3200) through a resistor pad
(R3321 - R3323) and a diplexer (C3320 and L3309). Matching to the input of the crystal filter is
provided by C3200 and L3200. The crystal filter provides the necessary selectivity and
intermodulation protection.
4.2
Receiver Back-End
(Refer to VHF Receiver Back End Schematic Diagram on page 6B-21)
The output of crystal filter Y3200 is matched to the input of IF amplifier transistor Q3200 by capacitor
C3203. Voltage supply to the IF amplifier is taken from the receive 5 volts (R5). The gain controlled IF
amplifer provides a maximum gain of about 10dB. The amplified IF signal is then coupled into
U3220(pin 3) via L3202, C3207, and C3230 which provides the matching for the IF amplifier and
U3220.
The IF signal applied to pin 3 of U3220 is amplified, down-converted, filtered, and demodulated, to
produce the recovered audio at pin 27 of U3220. This IF IC is electronically programmable, and the
amount of filtering (which is dependent on the radio channel spacing) is controlled by the
microprocessor. Additional filtering, once externally provided by the conventional ceramic filters, is
replaced by internal filters in the IF module (U3220).
The IF IC uses a type of direct conversion process, whereby the externally generated second LO
frequency is divided by two in U3220 so that it is very close to the first IF frequency. The IF IC (U3220)
synthesizes the second LO and phase-locks the VCO to track the first IF frequency. The second LO
is designed to oscillate at twice the first IF frequency because of the divide-by-two function in the IF
IC.
In the absence of an IF signal, the VCO will “search” for a frequency, or its frequency will vary close to
twice the IF frequency. When an IF signal is received, the VCO will lock onto the IF signal. The
second LO/VCO is a Colpitts oscillator built around transistor Q3270. The VCO has a varactor diode,
D3270, to adjust the VCO frequency. The control signal for the varactor is derived from a loop filter
consisting of C3278 to C3280, R3274 and R3275.
The IF IC (U3220) also performs several other functions. It provides a received signal-strength
indicator (RSSI) and a squelch output. The RSSI is a dc voltage monitored by the microprocessor,
and used as a peak indicator during the bench tuning of the receiver front-end varactor filter. The
RSSI voltage is also used to control the automatic gain control (AGC) circuit at the front-end.
The demodulated signal on pin 27 of U3220 is also used for squelch control. The signal is routed to
U404 (ASFIC) where squelch signal shaping and detection takes place. The demodulated audio
signal is also routed to U404 for processing before going to the audio amplifier for amplification.

4.3
Receiver
Automatic Gain Control Circuit
(Refer to VHF Receiver Front End Schematic Diagram on page 6B-20 and VHF Receiver Back End
Schematic Diagram on page 6B-21)
The front end automatic gain control circuit provides automatic reduction of gain, of the front end RF
amplifier via feedback. This action is necessary to prevent overloading of backend circuits. This is
achieved by drawing some of the output power from the RF amplifier output. At high radio
frequencies, capacitor C3327 provides the low impedance path to ground for this purpose. CR3302 is
a PIN diode used for switching the path on or off. A certain amount of forward biasing current is
needed to turn the PIN diode on. Transistor Q3301 provides this current.
Radio signal strength indicator, RSSI, a voltage signal, is used to drive Q3301 to saturation i.e.
turned on. RSSI is produced by U3220 and is proportional to the gain of the RF amplifier and the input
power to the radio.
Resistors R3304 and R3305 are voltage dividers designed to turn on Q3301 at certain RSSI levels. In
order to turn on Q3301 the voltage across R3305 must be greater or equal to the voltage across
R3324, plus the base-emitter voltage (Vbe) present at Q3301. Capacitor C3209 is used to dampen
any instability while the AGC is turning on. The current flowing into the collector of Q3301, a high
current gain NPN transistor, will be drawn through the PIN diode to turn it on. Maximum current
flowing through the PIN is limited by the resistors R3316, R3313, R3306 and R3324. C3326 is a
feedback capacitor used to provide some stability to this high gain stage.
An additional gain control circuit is formed by Q3201 and its associated circuitry. Resistors R3206 and
R3207 are voltage dividers designed to turn on Q3201 at a significantly higher RSSI level than the
level required to turn on PIN diode control transistor Q3301. In order to turn on Q3201 the voltage
across R3207 must be greater or equal to the voltage across R3208, plus the base-emitter voltage
(Vbe) present at Q3201. As current starts flowing into the collector of Q3201, it reduces the bias
voltage at the base of IF amplifier transistor Q3200 and in turn, the gain of the IF amplifier. The gain
can be controlled in a range of -30dB up to +10dB.

Figure 6-3: Frequency Generation Unit Block Diagram
The Frequency Generation Circuitry is composed of two main ICs, the Fractional-N synthesizer
(U3701), and the VCO/Buffer IC (U3801). Designed in conjunction to maximize compatibility, the two
ICs provide many of the functions that normally would require additional circuitry. The synthesizer
block diagram illustrates the interconnect and support circuitry used in the region. Refer to the
relevant schematics for the reference designators.
The synthesizer is powered by regulated 5V and 3.3V which come from U3711 and U3201
respectively. The synthesizer in turn generates a superfiltered 4.5V which powers U3801.
In addition to the VCO, the synthesizer must interface with the logic and ASFIC circuitry.
Programming for the synthesizer is accomplished through the data , clock and chip select lines from
the microprocessor. A 3.3V dc signal from synthesizer lock detect line indicates to the microprocessor
that the synthesizer is locked.
Transmit modulation from the ASFIC is supplied to pin10 of U3701. Internally the audio is digitized by
the Fractional-N and applied to the loop divider to provide the low-port modulation. The audio runs
through an internal attenuator for modulation balancing purposes before going out to the VCO.

(Refer toVHF Synthesizer Schematic Diagram on page 6B-22)
The Fractional-N Synthesizer uses a 16.8MHz crystal (Y3761) to provide a reference for the system.
The LVFractN IC (U3701) further divides this to 2.1MHz, 2.225MHz, and 2.4MHz as reference
frequencies. Together with C3761, C3762, C3763, R3761 and D3761 , they build up the reference
oscillator which is capable of 2.5ppm stability over temperatures of -30 to 85°C. It also provides
16.8MHz at pin 19 of U3701 to be used by ASFIC and LVZIF.
The loop filter which consist of C3721, C3722, R3721, R3722 and R3723 provides the necessary dc
steering voltage for the VCO and determines the amount of noise and spur passing through .
In achieving fast locking for the synthesizer, an internal adapt charge pump provides higher current at
pin 45 of U3701 to put synthesizer within the lock range. The required frequency is then locked by
normal mode charge pump at pin 43 .
Both the normal and adapt charge pumps get their supply from the capacitive voltage multiplier which
is made up of C3701 to C3704 and triple diodes D3701, D3702. Two 3.3V square waves ( 180 deg
out of phase) are first multiplied by four and then shifted, along with regulated 5V, to build up 13.5V at
pin 47 of U3701.

Figure 6-5: VCO Block Diagram
The VCOBIC (U3801) in conjunction with the Fractional-N synthesizer (U3701) generates RF in both
the receive and the transmit modes of operation. The TRB line (U3801 pin 19) determines which
oscillator and buffer will be enabled. A sample of the RF signal from the enabled oscillator is routed
from U3801 pin 12, through a low pass filter, to the prescaler input (U3701 pin 32). After frequency
comparison in the synthesizer, a resultant CONTROL VOLTAGE is received at the VCO. This voltage
is a DC voltage typically between 3.5V and 9.5V when the PLL is locked on frequency.
6B-12
Frequency Generation Circuitry
The RF section of the VCOBIC(U3801) is operated at 4.54 V (VSF), while the control section of the
VCOBIC and Fractional-N synthesizer (U3701) is operated at 3.3V. The operation logic is shown in
Table 6-1.

In the receive mode, U3801 pin 19 is low or grounded. This activates the receive VCO by enabling the
receive oscillator and the receive buffer of U3801. The RF signal at U3801 pin 8 is run through a
matching network. The resulting RF signal is the LO RF INJECTION and it is applied to the mixer at
T3302.
During the transmit condition, when PTT is depressed, 3.2 volts is applied to U3801 pin 19. This
activates the transmit VCO by enabling the transmit oscillator and the transmit buffer of U3801. The
RF signal at U3801 pin 10 is injected into the input of the PA module (U3501 pin16). This RF signal is
the TX RF INJECTION. Also in transmit mode, the audio signal to be frequency modulated onto the
carrier is received through U3701 pin 41.
When a high impedance is applied to U3801 pin19, the VCO is operating in BATTERY SAVER mode.
In this case, both the receive and transmit oscillators as well as the receive transmit and prescaler
buffer are turned off.

3.1
General
(Refer to Figure 6-1)
The UHF transmitter contains five basic circuits:
1. power amplifier
2. antenna switch
3. harmonic filter
4. antenna matching network
5. power control integrated circuit (PCIC).
3.1.1 Power Amplifier
The power amplifier consists of two devices:
1. 9Z67 LDMOS driver IC (U101) and
2. PRF1507 LDMOS PA (Q110).
The 9Z67 LDMOS driver IC contains a 2 stage amplification with a supply voltage of 7.3V.
This RF power amplifier is capable of supplying an output power of 0.3W (pin 6 and 7) with an input
signal of 2mW (3dBm) (pin16). The current drain would typically be 160mA while operating in the
frequency range of 450-527MHz.
The PRF1507 LDMOS PA is capable of supplying an output power of 7W with an input signal of
0.3W. The current drain would typically be 1300mA while operating in the frequency range of 450527MHz. The power output can be varied by changing the biasing voltage.
6C-4
Transmitter
3.1.2 Antenna Switch
The antenna switch circuit consists of two PIN diodes (CR101 and CR102), a pi network (C107, L104
and C106), and two current limiting resistors (R101, R170). In the transmit mode, B+ at PCIC (U102)
pin 23 will go low and turn on Q111 where a B+ bias is applied to the antenna switch circuit to bias the
diodes "on". The shunt diode (CR102) shorts out the receiver port, and the pi network, which
operates as a quarter wave transmission line, transforms the low impedance of the shunt diode to a
high impedance at the input of the harmonic filter. In the receive mode, the diodes are both off, and
hence, there exists a low attenuation path between the antenna and receiver ports.
3.1.3 Harmonic Filter
The harmonic filter consists of C104, L102, C103, L101 and C102. The design of the harmonic filter
for UHF is that of a modified Zolotarev design. It has been optimized for efficiency of the power
module. This type of filter has the advantage that it can give a greater attenuation in the stop-band for
a given ripple level. The harmonic filter insertion loss is typically less than 1.2dB.
3.1.4 Antenna Matching Network
A matching network which is made up of L116 is used to match the antenna's impedance to the
harmonic filter. This will optimize the performance of the transmitter and receiver into an antenna.
3.1.5 Power Control Integrated Circuit (PCIC)
The transmitter uses the Power Control IC (PCIC), U102 to regulate the power output of the radio.
The current to the final stage of the power module is supplied through R101, which provides a voltage
proportional to the current drain. This voltage is then fedback to the Automatic Level Control (ALC)
within the PCIC to regulate the output power of the transmitter.
The PCIC has internal digital to analog converters (DACs) which provide the reference voltage of the
control loop. The reference voltage level is programmable through the SPI line of the PCIC.
There are resistors and integrators within the PCIC, and external capacitors (C133, C134 and C135)
in controlling the transmitter rising and falling time. These are necessary in reducing the power
splatter into adjacent channels.
CR105 and its associated components are part of the temperature cut back circuitry. It senses the
printed circuit board temperature around the transmitter circuits and output a DC voltage to the PCIC.
If the DC voltage produced exceeds the set threshold in the PCIC, the transmitter output power will be
reduced so as to reduce the transmitter temperature.

4.1
Receiver Front-End
(Refer to UHF Band 2 Receiver Front End Schematic Diagram on page 6C-16 and UHF Band 2
Transmitter Schematic Diagram on page 6C-20)
The RF signal is received by the antenna and applied to a low-pass filter. For UHF, the filter consists
of L101, L102, C102, C103, C104. The filtered RF signal is passed through the antenna switch. The
antenna switch circuit consists of two PIN diodes(CR101 and CR102) and a pi network (C106, L104
and C107).The signal is then applied to a varactor tuned bandpass filter. The UHF bandpass filter
comprises of L301, L302, C302, C303, C304, CR301 and CR302. The bandpass filter is tuned by
applying a control voltage to the varactor diodes(CR301 and CR302) in the filter.
The bandpass filter is electronically tuned by the DACRx from IC404 which is controlled by the
microprocessor. Depending on the carrier frequency, the DACRx will supply the tuned voltage to the
varactor diodes in the filter. Wideband operation of the filter is achieved by shifting the bandpass filter
across the band.
The output of the bandpass filter is coupled to the RF amplifier transistor Q301 via C307. After being
amplified by the RF amplifier, the RF signal is further filtered by a second varactor tuned bandpass
filter, consisting of L306, L307, C313, C317, CR304 and CR305.
Both the pre and post-RF amplifier varactor tuned filters have similar responses. The 3 dB bandwidth
of the filter is about 50 MHz. This enables the filters to be electronically controlled by using a single
control voltage which is DACRx .
6C-6
Receiver
The output of the post-RF amplifier filter which is connected to the passive double balanced mixer
consists of T301, T302 and CR306. Matching of the filter to the mixer is provided by C381. After
mixing with the first LO signal from the voltage controlled oscillator (VCO) using low side injection, the
RF signal is down-converted to the 45.1 MHz IF signal.
The IF signal coming out of the mixer is transfered to the crystal filter (FL301) through a resistor pad
and a diplexer (C322 and L310). Matching to the input of the crystal filter is provided by C324 and
L311. The crystal filter provides the necessary selectivity and intermodulation protection.
4.2
Receiver Back-End
(Refer to UHF Band 2 Receiver Back End Schematic Diagram on page 6C-17)
The output of crystal filter FL301 is matched to the input of IF amplifier transistor Q302 by
components R352 and C325. Voltage supply to the IF amplifier is taken from the receive 5 volts (R5).
The IF amplifer provides a gain of about 7dB. The amplified IF signal is then coupled into U301(pin 3)
via C330, C338 and L330 which provides the matching for the IF amplifier and U301.
The IF signal applied to pin 3 of U301 is amplified, down-converted, filtered, and demodulated, to
produce the recovered audio at pin 27 of U301. This IF IC is electronically programmable, and the
amount of filtering (which is dependent on the radio channel spacing) is controlled by the
microprocessor. Additional filtering, once externally provided by the conventional ceramic filters, is
replaced by internal filters in the IF module (U301).
The IF IC uses a type of direct conversion process, whereby the externally generated second LO
frequency is divided by two in U301 so that it is very close to the first IF frequency. The IF IC (U301)
synthesizes the second LO and phase-locks the VCO to track the first IF frequency. The second LO
is designed to oscillate at twice the first IF frequency because of the divide-by-two function in the IF
IC.
In the absence of an IF signal, the VCO will “search” for a frequency, or its frequency will vary close to
twice the IF frequency. When an IF signal is received, the VCO will lock onto the IF signal. The
second LO/VCO is a Colpitts oscillator built around transistor Q320. The VCO has a varactor diode,
CR310, to adjust the VCO frequency. The control signal for the varactor is derived from a loop filter
consisting of C362, C363, C364, R320 and R321.
The IF IC (U301) also performs several other functions. It provides a received signal-strength
indicator (RSSI) and a squelch output. The RSSI is a dc voltage monitored by the microprocessor,
and used as a peak indicator during the bench tuning of the receiver front-end varactor filter. The
RSSI voltage is also used to control the automatic gain control (AGC) circuit at the front-end.
The demodulated signal on pin 27 of U301 is also used for squelch control. The signal is routed to
U404 (ASFIC) where squelch signal shaping and detection takes place. The demodulated audio
signal is also routed to U404 for processing before going to the audio amplifier for amplification.
Receiver
4.3
6C-7
Automatic Gain Control Circuit
(Refer to UHF Band 2 Receiver Front End Schematic Diagram on page 6C-16)
The front end automatic gain control circuit is to provide automatic gain reduction of the front end RF
amplifier via feedback. This action is necessary to prevent overloading of backend circuits. This is
achieved by drawing some of the output power from the RF amplifier’s output. At high radio
frequencies, capacitor C331 provides the low impedance path to ground for this purpose. CR308 is a
PIN diode used for switching the path on or off. A certain amount of forward biasing current is needed
to turn the PIN diode on. Transistors Q315 provides this current where upon saturation, current will
flow via R347, PIN diode, collector and emitter of Q315 and R319 before going to ground. Q315 is an
NPN transistor used for switching here. Maximum current flowing through the PIN is mainly limited by
the resistor R319.
Radio signal strength indicator, RSSI, a voltage signal, is used to drive Q315 to saturation hence
turning it on. RSSI is produced by U301 and is proportional to the gain of the RF amplifier and the
input RF signal power to the radio.
Resistor network at the input to the base of Q315 is scaled to turn on Q315, hence activating the
AGC, at certain RSSI levels. In order to turn on Q315, the voltage across the transistor’s base to
ground must be greater or equal to the voltage across R319, plus the base-emitter voltage (Vbe)
present at Q315. The resistor network with thermistor RT300 is capable of providing temperature
compensation to the AGC circuit, as RSSI generated by U301 is lower at cold temperatures
compared to normal operation at room temperature. Resistor R300 and capacitor C397 form an R-C
network used to dampen any transient instability while the AGC is turning on.

Figure 6-3: Frequency Generation Unit Block Diagram
The Frequency Generation Circuitry is composed of two main ICs, the Fractional-N synthesizer
(U201), and the VCO/Buffer IC (U241). Designed in conjunction to maximize compatibility, the two
ICs provide many of the functions that normally would require additional circuitry. The synthesizer
block diagram illustrates the interconnect and support circuitry used in the region. Refer to the
relevant schematics for the reference designators.
The synthesizer is powered by regulated 5V and 3.3V which come from U247 and U248 respectively.
The synthesizer in turn generates a superfiltered 4.5V which powers U241.
In addition to the VCO, the synthesizer must interface with the logic and ASFIC circuitry.
Programming for the synthesizer is accomplished through the data , clock and chip select lines from
the microprocessor. A 3.3V dc signal from synthesizer lock detect line indicates to the microprocessor
that the synthesizer is locked.
Transmit modulation from the ASFIC is supplied to pin10 of U201. Internally the audio is digitized by
the Fractional-N and applied to the loop divider to provide the low-port modulation. The audio runs
through an internal attenuator for modulation balancing purposes before going out to the VCO.
Frequency Generation Circuitry
5.1
6C-9
Synthesizer
(Refer to UHF Band 2 Synthesizer Schematic Diagram on page 6C-18)
The Fractional-N Synthesizer uses a 16.8MHz crystal (FL201) to provide a reference for the system.
The LVFractN IC (U201) further divides this to 2.1MHz, 2.225MHz, and 2.4MHz as reference
frequencies. Together with C206, C207, C208, R204 and CR203 , they build up the reference
oscillator which is capable of 2.5ppm stability over temperatures of -30 to 85°C. It also provides
16.8MHz at pin 19 of U201 to be used by ASFIC and LVZIF.
The loop filter which consist of C231, C232, C233, R231, R232 and R233 provides the necessary dc
steering voltage for the VCO and determines the amount of noise and spur passing through .
In achieving fast locking for the synthesizer, an internal adapt charge pump provides higher current at
pin 45 of U201 to put synthesizer within the lock range. The required frequency is then locked by
normal mode charge pump at pin 43 .
Both the normal and adapt charge pumps get their supply from the capacitive voltage multiplier which
is made up of C258, C259, C228, triple diode CR201 and level shifters U210 and U211. Two 3.3V
square waves ( 180 deg out of phase) are first shifted to 5V, then along with regulated 5V , put
through arrays of diodes and capacitors to build up 13.3V at pin 47 of U201.

The VCOBIC (U241) in conjunction with the Fractional-N synthesizer (U201) generates RF in both
the receive and the transmit modes of operation. The TRB line (U241 pin 19) determines which
oscillator and buffer will be enabled. A sample of the RF signal from the enabled oscillator is routed
from U241 pin 12, through a low pass filter, to the prescaler input (U201 pin 32). After frequency
comparison in the synthesizer, a resultant CONTROL VOLTAGE is received at the VCO. This
voltage is a DC voltage between 3.5V and 9.5V when the PLL is locked on frequency.
Frequency Generation Circuitry
6C-11
The VCOBIC(U241) is operated at 4.54 V (VSF) and Fractional-N synthesizer (U201) at 3.3V. This
difference in operating voltage requires a level shifter consisting of Q260 and Q261 on the TRB line.
The operation logic is shown in Table 6-1.

In the receive mode, U241 pin 19 is low or grounded. This activates the receive VCO by enabling the
receive oscillator and the receive buffer of U241. The RF signal at U241 pin 8 is run through a
matching network. The resulting RF signal is the LO RF INJECTION and it is applied to the mixer at
T302 (refer to UHF Band 2 Receiver Front End Schematic Diagram on page 6C-16).
During the transmit condition, when PTT is depressed, five volts is applied to U241 pin 19. This
activates the transmit VCO by enabling the transmit oscillator and the transmit buffer of U241. The RF
signal at U241 pin 10 is injected into the input of the PA module (U101 pin16). This RF signal is the
TX RF INJECTION. Also in transmit mode, the audio signal to be frequency modulated onto the
carrier is received through the U201 pin 41.
When a high impedance is applied to U241 pin19, the VCO is operating in BATTERY SAVER mode.
In this case, both the receive and transmit oscillators as well as the receive transmit and prescaler
buffer are turned off.

1. power amplifier
2. antenna switch
3. harmonic filter
4. antenna matching network
5. power control integrated circuit (PCIC).
3.1.1 Power Amplifier
The power amplifier consists of two devices:
1. 9Z67 LDMOS driver IC (U101) and
2. PRF1507 LDMOS PA (Q110).
The 9Z67 LDMOS driver IC contains a 2 stage amplification with a supply voltage of 7.3V.
This RF power amplifier is capable of supplying an output power of 0.3W (pin 6 and 7) with an input
signal of 2mW (3dBm) (pin16). The current drain would typically be 160mA while operating in the
frequency range of 330-400MHz.
The PRF1507 LDMOS PA is capable of supplying an output power of 7W with an input signal of
0.3W. The current drain would typically be 1300mA while operating in the frequency range of 330400MHz. The power output can be varied by changing the biasing voltage.

Transmitter
3.1.2 Antenna Switch
The antenna switch circuit consists of two PIN diodes (CR101 and CR102), a pi network (C107, L104
and C106), and two current limiting resistors (R101, R170). In the transmit mode, B+ at PCIC (U102)
pin 23 will go low and turn on Q111 where a B+ bias is applied to the antenna switch circuit to bias the
diodes "on". The shunt diode (CR102) shorts out the receiver port, and the pi network, which
operates as a quarter wave transmission line, transforms the low impedance of the shunt diode to a
high impedance at the input of the harmonic filter. In the receive mode, the diodes are both off, and
hence, there exists a low attenuation path between the antenna and receiver ports.
3.1.3 Harmonic Filter
The harmonic filter consists of C104, L102, C103, L101 and C102. The design of the harmonic filter
for VHF is that of a modified Zolotarev design. It has been optimized for efficiency of the power
module. This type of filter has the advantage that it can give a greater attenuation in the stop-band for
a given ripple level. The harmonic filter insertion loss is typically less than 1.2dB.
3.1.4 Antenna Matching Network
A matching network which is made up of L116 is used to match the antenna's impedance to the
harmonic filter. This will optimize the performance of the transmitter and receiver into an antenna.
3.1.5 Power Control Integrated Circuit (PCIC)
The transmitter uses the Power Control IC (PCIC), U102 to regulate the power output of the radio.
The current to the final stage of the power module is supplied through R101, which provides a voltage
proportional to the current drain. This voltage is then fedback to the Automatic Level Control (ALC)
within the PCIC to regulate the output power of the transmitter.
The PCIC has internal digital to analog converters (DACs) which provide the reference voltage of the
control loop. The reference voltage level is programmable through the SPI line of the PCIC.
There are resistors and integrators within the PCIC, and external capacitors (C133, C134 and C135)
in controlling the transmitter rising and falling time. These are necessary in reducing the power
splatter into adjacent channels.
CR105 and its associated components are part of the temperature cut back circuitry. It senses the
printed circuit board temperature around the transmitter circuits and output a DC voltage to the PCIC.
If the DC voltage produced exceeds the set threshold in the PCIC, the transmitter output power will be
reduced so as to reduce the transmitter temperature.

Receiver Front-End
(Refer to 330-400MHz Receiver Front End Schematic Diagram on page 6D-16 and 330-400MHz
Transmitter Schematic Diagram on page 6D-20)
The RF signal is received by the antenna and applied to a low-pass filter. For VHF, the filter consists
of L101, L102, C102, C103, C104. The filtered RF signal is passed through the antenna switch. The
antenna switch circuit consists of two PIN diodes(CR101 and CR102) and a pi network (C106, L104
and C107).The signal is then applied to a varactor tuned bandpass filter. The VHF bandpass filter
comprises of L301, L302, C302, C303, C304, CR301 and CR302. The bandpass filter is tuned by
applying a control voltage to the varactor diodes(CR301 and CR302) in the filter.
The bandpass filter is electronically tuned by the DACRx from U404 which is controlled by the
microprocessor. Depending on the carrier frequency, the DACRx will supply the tuned voltage to the
varactor diodes in the filter. Wideband operation of the filter is achieved by shifting the bandpass filter
across the band.
The output of the bandpass filter is coupled to the RF amplifier transistor Q301 via C307. After being
amplified by the RF amplifier, the RF signal is further filtered by a second varactor tuned bandpass
filter, consisting of L306, L307, C313, C317, CR304 and CR305.
Both the pre and post-RF amplifier varactor tuned filters have similar responses. The 3 dB bandwidth
of the filter is about 50 MHz. This enables the filters to be electronically controlled by using a single
control voltage which is DACRx .
6D-6
Receiver
The output of the post-RF amplifier filter which is connected to the passive double balanced mixer
consists of T301, T302 and CR306. Matching of the filter to the mixer is provided by C381. After
mixing with the first LO signal from the voltage controlled oscillator (VCO) using low side injection, the
RF signal is down-converted to the 45.1 MHz IF signal.
The IF signal coming out of the mixer is transfered to the crystal filter (FL301) through a resistor pad
and a diplexer (C322 and L310). Matching to the input of the crystal filter is provided by C324 and
L311. The crystal filter provides the necessary selectivity and intermodulation protection.
4.2
Receiver Back-End
(Refer to 330-400MHz Receiver Back End Schematic Diagram on page 6D-17)
The output of crystal filter FL301 is matched to the input of IF amplifier transistor Q302 by
components R352 and C325. Voltage supply to the IF amplifier is taken from the receive 5 volts (R5).
The IF amplifer provides a gain of about 7dB. The amplified IF signal is then coupled into U301(pin 3)
via C330, C338 and L330 which provides the matching for the IF amplifier and U301.
The IF signal applied to pin 3 of U301 is amplified, down-converted, filtered, and demodulated, to
produce the recovered audio at pin 27 of U301. This IF IC is electronically programmable, and the
amount of filtering (which is dependent on the radio channel spacing) is controlled by the
microprocessor. Additional filtering, once externally provided by the conventional ceramic filters, is
replaced by internal filters in the IF module (U301).
The IF IC uses a type of direct conversion process, whereby the externally generated second LO
frequency is divided by two in U301 so that it is very close to the first IF frequency. The IF IC (U301)
synthesizes the second LO and phase-locks the VCO to track the first IF frequency. The second LO
is designed to oscillate at twice the first IF frequency because of the divide-by-two function in the IF
IC.
In the absence of an IF signal, the VCO will “search” for a frequency, or its frequency will vary close to
twice the IF frequency. When an IF signal is received, the VCO will lock onto the IF signal. The
second LO/VCO is a Colpitts oscillator built around transistor Q320. The VCO has a varactor diode,
CR310, to adjust the VCO frequency. The control signal for the varactor is derived from a loop filter
consisting of C362, C363, C364, R320 and R321.
The IF IC (U301) also performs several other functions. It provides a received signal-strength
indicator (RSSI) and a squelch output. The RSSI is a dc voltage monitored by the microprocessor,
and used as a peak indicator during the bench tuning of the receiver front-end varactor filter. The
RSSI voltage is also used to control the automatic gain control (AGC) circuit at the front-end.
The demodulated signal on pin 27 of U301 is also used for squelch control. The signal is routed to
U404 (ASFIC) where squelch signal shaping and detection takes place. The demodulated audio
signal is also routed to U404 for processing before going to the audio amplifier for amplification.

6D-7
Automatic Gain Control Circuit
(Refer to 330-400MHz Receiver Front End Schematic Diagram on page 6D-16)
The front end automatic gain control circuit is to provide automatic gain reduction of the front end RF
amplifier via feedback. This action is necessary to prevent overloading of backend circuits. This is
achieved by drawing some of the output power from the RF amplifier’s output. At high radio
frequencies, capacitor C331 provides the low impedance path to ground for this purpose. CR308 is a
PIN diode used for switching the path on or off. A certain amount of forward biasing current is needed
to turn the PIN diode on. Transistors Q315 provides this current where upon saturation, current will
flow via R347, PIN diode, collector and emitter of Q315 and R319 before going to ground. Q315 is an
NPN transistor used for switching here. Maximum current flowing through the PIN is mainly limited by
the resistor R319.
Radio signal strength indicator, RSSI, a voltage signal, is used to drive Q315 to saturation hence
turning it on. RSSI is produced by U301 and is proportional to the gain of the RF amplifier and the
input RF signal power to the radio.
Resistor network at the input to the base of Q315 is scaled to turn on Q315, hence activating the
AGC, at certain RSSI levels. In order to turn on Q315, the voltage across the transistor’s base to
ground must be greater or equal to the voltage across R319, plus the base-emitter voltage (Vbe)
present at Q315. The resistor network with thermistor RT300 is capable of providing temperature
compensation to the AGC circuit, as RSSI generated by U301 is lower at cold temperatures
compared to normal operation at room temperature. Resistor R300 and capacitor C397 form an R-C
network used to dampen any transient instability while the AGC is turning on.

Figure 6-3: Frequency Generation Unit Block Diagram
The Frequency Generation Circuitry is composed of two main ICs, the Fractional-N synthesizer
(U201), and the VCO/Buffer IC (U241). Designed in conjunction to maximize compatibility, the two
ICs provide many of the functions that normally would require additional circuitry. The synthesizer
block diagram illustrates the interconnect and support circuitry used in the region. Refer to the
relevant schematics for the reference designators.
The synthesizer is powered by regulated 5V and 3.3V which come from U247 and U248 respectively.
The synthesizer in turn generates a superfiltered 4.5V which powers U241.
In addition to the VCO, the synthesizer must interface with the logic and ASFIC circuitry.
Programming for the synthesizer is accomplished through the data , clock and chip select lines from
the microprocessor. A 3.3V dc signal from synthesizer lock detect line indicates to the microprocessor
that the synthesizer is locked.
Transmit modulation from the ASFIC is supplied to pin10 of U201. Internally the audio is digitized by
the Fractional-N and applied to the loop divider to provide the low-port modulation. The audio runs
through an internal attenuator for modulation balancing purposes before going out to the VCO.
Frequency Generation Circuitry

6D-9
Synthesizer
(Refer to 330-400MHz Synthesizer Schematic Diagram on page 6D-18)
The Fractional-N Synthesizer uses a 16.8MHz crystal (FL201) to provide a reference for the system.
The LVFractN IC (U201) further divides this to 2.1MHz, 2.225MHz, and 2.4MHz as reference
frequencies. Together with C206, C207, C208, R204 and CR203 , they build up the reference
oscillator which is capable of 2.5ppm stability over temperatures of -30 to 85°C. It also provides
16.8MHz at pin 19 of U201 to be used by ASFIC and LVZIF.
The loop filter which consist of C231, C232, C233, R231, R232 and R233 provides the necessary dc
steering voltage for the VCO and determines the amount of noise and spur passing through .
In achieving fast locking for the synthesizer, an internal adapt charge pump provides higher current at
pin 45 of U201 to put synthesizer within the lock range. The required frequency is then locked by
normal mode charge pump at pin 43 .
Both the normal and adapt charge pumps get their supply from the capacitive voltage multiplier which
is made up of C258, C259, C228, triple diode CR201 and level shifters U210 and U211. Two 3.3V
square waves ( 180 deg out of phase) are first shifted to 5V, then along with regulated 5V , put
through arrays of diodes and capacitors to build up 13.3V at pin 47 of U201.

Figure 6-5 VCO Block Diagram
The VCOBIC (U241) in conjunction with the Fractional-N synthesizer (U201) generates RF in both
the receive and the transmit modes of operation. The TRB line (U241 pin 19) determines which
oscillator and buffer will be enabled. A sample of the RF signal from the enabled oscillator is routed
from U241 pin 12, through a low pass filter, to the prescaler input (U201 pin 32). After frequency
comparison in the synthesizer, a resultant CONTROL VOLTAGE is received at the VCO. This
voltage is a DC voltage between 3.5V and 9.5V when the PLL is locked on frequency.
Frequency Generation Circuitry
6D-11
The VCOBIC(U241) is operated at 4.54 V (VSF) and Fractional-N synthesizer (U201) at 3.3V. This
difference in operating voltage requires a level shifter consisting of Q260 and Q261 on the TRB line.
The operation logic is shown in Table 6-1.

In the receive mode, U241 pin 19 is low or grounded. This activates the receive VCO by enabling the
receive oscillator and the receive buffer of U241. The RF signal at U241 pin 8 is run through a
matching network. The resulting RF signal is the LO RF INJECTION and it is applied to the mixer at
T302 (refer to 330-400MHz Receiver Front End Schematic Diagram on page 6D-16).
During the transmit condition, when PTT is depressed, five volts is applied to U241 pin 19. This
activates the transmit VCO by enabling the transmit oscillator and the transmit buffer of U241. The RF
signal at U241 pin 10 is injected into the input of the PA module (U101 pin16). This RF signal is the
TX RF INJECTION. Also in transmit mode, the audio signal to be frequency modulated onto the
carrier is received through the U201 pin 41.
When a high impedance is applied to U241 pin19, the VCO is operating in BATTERY SAVER mode.
In this case, both the receive and transmit oscillators as well as the receive transmit and prescaler
buffer are turned off.

Figure 6-1: Lowband Transmitter Block Diagram
3.1
General
(Refer to Figure 6-1)
The Lowband transmitter consists of the following basic circuits:
1. power amplifier (PA)
2. antenna switch
3. harmonic filter
4. antenna matching network
5. power control integrated circuit (PCIC).
3.1.1 Power Amplifier
The power amplifier consists of two LDMOS devices:
1. PA driver, U101 and
2. PA final stage, Q100.
The LDMOS driver (U101) provides 2-stage amplification using a supply voltage of 7.3V. The
amplifier is capable of supplying an output power of 0.3W (pins 6 and 7) with an input signal of 2mW
at (pin16). The current drain is typically 120mA while operating in the frequency range of 29.7 - 50
MHz. The power output of this stage is varied by the power control loop which controls the voltage on
pin 1.
The LDMOS PA is capable of supplying an output power of 8W with an input signal of 0.3W. The
current drain is typically 2000 mA while operating in the frequency range of 29.7 - 50 MHz. The final
stage gate is bias by a voltage from PCIC pin 24. This voltage is the output of a programmable DAC
inside the PCIC and the output is adjustable with the radio tuner.
Transmitter
6E-5
3.1.2 Antenna Switch
The antenna switch circuit consists of two pin diodes (D100 and D101), a RF network (C147 and
L103), and a DC feed network (L104, C144 and current limiting resistor R101). In the transmit mode,
PCIC (U102) pin 32 goes high supplying current via the feed network to bias the diodes “on”. The
shunt diode (D101) shorts out the receiver port and L103 is connected from the RF path to ground.
L103 and the input capacitance of the lowpass filter form a parallel resonant circuit, effectively
disconnecting the receiver port from the antenna while not loading the transmit path. In the receive
mode, pin 32 goes low and the.the diodes are off. D100 looks like a high impedance disconnecting
the transmitter from the antenna while L103 and C147 form a series resonant circuit to connect the
receiver to the antenna.
3.1.3 Harmonic Filter
The harmonic filter consists of components C103, C106, C107,C110, C111, C114, C115 and 3
inductors which are a part of the SH100 assembly. The harmonic filter for lowband is pole zero design
which give greater attenuation lower in frequency where the harmonic energy of the transmitter is the
greatest and less attenuation high in frequency where there is less harmonic energy. The harmonic
filter insertion loss is typically less than 0.8 dB
3.1.4 Antenna Matching Network
The antenna matching network (T100) matches the antenna's impedance with the harmonic filter to
optimize the performance of the transmitter and receiver.
3.1.5 Power Control Integrated Circuit (PCIC)
The transmitter uses the PCIC (U102) to regulate the power output of the radio. To accomplish this,
the voltage across R102 is sensed. This voltage drop is directly proportional to the current drawn in
the final stage of the transmitter. This voltage is compared to a programmable reference inside the
PCIC and the voltage on PCIC pin 4 adjusted. Pin 4 connects to the PA driver IC (U101) pin 1 via
resistor R100 and varies RF output power of the driver. This controls the current drain of the final
stage and sets the output power.
3.1.6 Temperature Cut Back Circuit
Temperature sensor VR101 and associated components are part of a temperature cut back circuit.
This circuit senses the printed circuit board temperature around the transmitter circuits and outputs a
DC voltage to the PCIC. If the DC voltage produced exceeds the set threshold of the PCIC, the
transmitter output power decreases to reduce the transmitter temperature.

Receiver Front-End
The RF signal received by the antenna is routed through the transmitter lowpass filter and antenna
switch. These circuits are described in the transmitter section.The signal next passes through a
highpass filter consisting of L501, L502, C538, C533 and C504. This filter serves to reject below band
signals and has a 3 dB corner frequency of 27 MHz.
The output of the highpass filter is connected to an RF amp consisting of Q509 and associated
biasing components. This is a BJT amplifier powered off 5 volts and has 13 dB of gain. The amplifier
drives a lowpass filter consisting of L503, L504 L507, C534, C535, C536, C537 and C515. This filter
is a pole zero design that filters off harmonic components from the RF amp. The 3 dB corner of this
filter is at 56 MHz.
The output of the lowpass filter is connected to the passive double balanced mixer consisting of
components T501, T502, and D501. After mixing with the first local oscillator up-converted to a
109.65 MHz IF signal.
The IF signal coming out of the mixer is transferred to the crystal filter (FL301) through a resistor pad
(R507, R508 and R509) and a diplexer (C516 and L508). Matching to the input of the crystal filter is
provided by L301, L302, C301 and C302. The 3 pole crystal filter provides the necessary selectivity
and intermodulation protection.
Receiver
4.2
6E-7
Receiver Back-End
The output of crystal filter FL301 is connected to the input of IF amplifier transistor U301. Components
L303 and C348 and R301 form the termination for the crystal filter and the signal is coupled to one
gate of U301 by C303. The IF amplifier is a dual gate MOSFET powered off of the 5 volt supply. The
first gate receives the IF signal as indicated previously. The second gate receives a DC voltage from
U302 which serves as an AGC control signal. This signal reduces the gain of the IF amplifier to
prevent overload of the IF IC, U303. The gain can be varied from a maximum of 13 dB to an
attenuation of 55 dB. The output IF signal from U301 is coupled into U303 (pin 3) via C306, R304 and
L304 which provides matching for the IF amplifier and U303.
The IF signal applied to pin 3 of U303 is amplified, down-converted, filtered, and demodulated, to
produce recovered audio at pin 27 of U303. This IF IC is electronically programmable, and the
amount of filtering, which is dependent on the radio channel spacing, is controlled by the
microprocessor. Additional filtering, once externally provided by the conventional ceramic filters, is
replaced by internal filters in IF IC U303.
The IF IC uses a type of direct conversion process, whereby the externally generated second LO
frequency is divided by two in U303 so that it is very close to the first IF frequency. The IF IC (U303)
synthesizes the second LO and phase-locks the VCO to track the first IF frequency. The second LO is
designed to oscillate at twice the first IF frequency because of the divide-by-two function in the IF IC.
In the absence of an IF signal, the VCO searches for a frequency, or its frequency will vary close to
twice the IF frequency. When an IF signal is received, the VCO locks onto the IF signal. The second
LO/VCO is a Colpitts oscillator built around transistor Q301. The VCO has a varactor diode, CR301,
to adjust the VCO frequency. The control signal for the varactor is derived from a loop filter consisting
of components C308, C309, and R310.
The IF IC (U303) also performs several other functions. It provides a received signal-strength
indicator (RSSI) and a squelch output. The RSSI voltage is also used to control the automatic gain
control (AGC) circuit at the back end.
The demodulated signal on pin 27 of U303 is also used for squelch control. The signal is routed to
U404 (ASFIC) where squelch signal shaping and detection takes place. The demodulated audio
signal is also routed to U404 for processing before going to the audio amplifier for amplification.
4.3
Automatic Gain Control Circuit
The automatic gain control circuit provides automatic reduction of gain to prevent overloading of
backend circuits. This is achieved by lowering the voltage on one gate of U301 which will reduce the
drain current in that part and lower its gain.
The Radio Signal Strength Indicator (RSS I) voltage signal for the IF IC (U303) is used to drive the
AGC processing circuitry consisting of R306, R307, R308, R309 C307 and U302. As the received
signal gets stronger, the RSSI line will rise. When the RSSI line passes a certain threshold, the
voltage at the output of U302 will begin to drop. This voltage is connected to one gate of IF amplifier
U301 through resistor R305. As this voltage decreases, it will lower the drain current in U301 and
reduce the gain of the stage. This will limit the power incident on the IF IC, U303.

Figure 6-3: Lowband Frequency Generation Unit Block Diagram
The frequency generation circuit, shown in Figure 6-3 , is composed of Low Voltage Fractional-N
synthesizer U205 and discrete RX VCO, TX VCO.and buffers as well other supporting circuitry. The
synthesizer block diagram illustrates the interconnect and support circuitry used in the region. Refer
to the schematic for the reference designators.
The synthesizer is powered by regulated 5V and 3.3V. The 5 volt signal to the synthesizer as well as
the rest of the radio is provided by U204. The 3.3 v signal is provided from U400 in the controller. The
5V signal goes to pins 13 and 30 while the 3.3V signal goes to pins 5, 20, 34 and 36 of U201. The
synthesizer in turn generates a superfiltered 4.3V which powers the VCOs and buffers.
In addition to the VCO, the synthesizer also interfaces with the logic and ASFIC circuitry.
Programming for the synthesizer is accomplished through the data, clock and chip select lines (pins
7, 8 and 9) from the microprocessor, U409. A 3.3V dc signal from pin 4 indicates to the
microprocessor that the synthesizer is locked.
Transmit modulation from the ASFIC is supplied to pin10 of U205. Internally the audio is digitized by
the Fractional-N and applied to the loop divider to provide the low-port modulation. The audio runs
through an internal attenuator for modulation balancing purposes before going out at pin 41 to the
VCO.
Frequency Generation Circuitry

6E-9
Synthesizer
The Fractional-N synthesizer, shown in Figure 6-4, uses a 17.0 MHz crystal (Y201) to provide a
reference for the system. Along with being used in the LVFracN, the 17.0 MHz signal is provided at
pin 19 of U205 for use by the ASFIC and LVZIF.
The LVFractN IC (U205) further divides this by 8 internally to give 2.125 MHz to be used as the
reference frequency in the frequency synthesis. While UHF and VHF can use other references,
(divide by 7 or divide by 7/8), only the divide by 8 function is valid for lowband.
The internal oscillator device in the LVFracN together with C236, C237, C242, R219, CR211and Y201
comprise the reference oscillator. This oscillator is temperature compensated is capable of 2.5 ppm
stability over temperatures of -30 to 85°C. There is temperature compensation information that is
unique to each crystal contained on Y201 that is programmed into the radio when built.
The loop filter consists of components C256, C257, C259, R224, R225 and R228. This circuit
provides the necessary dc steering voltage for the VCO and determines the amount of noise and spur
passing through.
To achieve fast locking for the synthesizer, an internal adapt charge pump provides higher current at
pin 45 of U205 to put the synthesizer within lock range. The required frequency is then locked by
normal mode charge pump at pin 43.
Both the normal and adapt charge pumps get their supply from the inductive voltage multiplier made
up of C240, C246, C247, C249, D201, and L223. This circuit provides 13.3V at pin 47 of U205.

5.2.1 Receive VCO
The receive VCO is a Colpitts type design and using two active devices in parallel, Q202 and Q204.
The oscillator is powered off of the 4.3 volt super filter supply when the AUX3 line goes low. The
oscillator operates from 139 to 160 MHz, and the frequency is tuned by varactor diodes CR201 and
CR202.
5.2.2 Transmit VCO
The transmit VCO is a Hartley type design with active devices Q203. The oscillator is powered off of
the 4.3 volt super filter supply when the AUX2 line goes low. The oscillator operates from 29.7 to 42
MHz for Range 1 and 35 to 50 MHz for Range 2. The frequency is tuned by varactor diodes in U203.
Note that the values of the inductive tap, L208 and L209, and the capacitor C215 which couples the
varactor to the oscillator tank vary between the ranges.
5.2.3 Buffer
Both the receive and transmit VCO are fed to a buffer amplifier Q201. This is a BJT amplifier that
boosts the signal levels to +4 dBm and provides reverse isolation to the oscillators. The amplifier is
powered off the 4.3 volt super filter supply and the feed network is combined with the transmit filter.
5.2.4 Diplexer and Output Filters
The output of the buffer drives a pair of parallel filters. One filter is a lowpass filter in the TX pass that
passes 29.7 - 50 MHz signals for the transmitter into the power amplifier while rejecting the receive
LO injection signals at 139 - 160 MHz. This filter is comprised of L204, L211, L212, C230 and C231.
The other filter is a highpass filter which passes 139 - 160 MHz signals for the receive LO into the
mixer while rejecting the transmit injection signals at 29.7 -50 MHz. This filter is comprised of
C228,C229,C235 and L215.
5.2.5 Prescalar Feedback
The prescalar input signal for receive and transmit is tapped off of the outputs of each filter by
resistors R234 and R238. This signal is routed to U205 pin 32. After frequency comparison in the
synthesizer, current is transferred in the loop filter and a control voltage is generated at the output of
the loop filter to adjust the frequency of the VCO. This voltage is a DC voltage between 3.5V and 9.5V
when the PLL is locked on frequency.

Notes For All Schematics and Circuit Boards
* Component is frequency sensitive. Refer to the Electrical Parts List for value and usage.
1. Unless otherwise stated, resistances are in Ohms (k = 1000), and capacitances are in picofarads
(pF) or microfarads (µF).
2. DC voltages are measured from point indicated to chassis ground using a Motorola DC multimeter or equivalent. Transmitter measurements should be made with a 1.2 µH choke in series with
the voltage probe to prevent circuit loading.
