Your Motorola radio is designed to comply with the following national and international standards and
guidelines regarding exposure of human beings to radio frequency electromagnetic energy (EME):
To assure optimal radio performance and make sure human exposure to radio frequency
electromagnetic energy is within the guidelines set forth in the above standards, always
adhere to the following procedures:
ht
tp
Two-way Radio Operation
When using your radio, hold the radio in a vertical position
with the microphone one to two inches (2.5 to 5 centimeters)
away from the lips.
2.5 to 5.0 cm
(1 to 2 in.)
Body-worn Operation
To maintain compliance with FCC RF exposure guidelines, if you
wear a radio on your body when transmitting, 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 positions along side of the head in the phone mode or in
ii
SAFETY INFORMATION
front of the face in the two-way radio mode, then ensure the antenna and radio is kept the
following minimum distances from the body when transmitting:
•
•
Phone or Two-way radio mode: one inch (2.5 centimeters)
Data operation using any data feature with or without an accessory cable: one inch (2.5
centimeters)
Antenna Care
Use only the supplied or an approved replacement antenna.
Unauthorized antennas, modifications, or attachments could damage the radio and may violate FCC
regulations.
et
DO NOT hold the antenna when the radio is “IN USE”. Holding the antenna affects call quality and
may cause the radio to operate at a higher power level than needed.
.n
Approved Accessories

ELECTROMAGNETIC INTERFERENCE/COMPATIBILITY
68
For a list of approved Motorola accessories look in the appendix or accessory section of your radio’s
User Guide.
NOTE Nearly every electronic device is susceptible to electromagnetic interference (EMI) if inade-
ad
quately shielded, designed, or otherwise configured for electromagnetic compatibility.
yr
Facilities
w
.m
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
Medical Devices
•
://
w
w
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.
Pacemakers
ht
tp
The Health Industry Manufacturers Association 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 six 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.
SAFETY INFORMATION
•
iii
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.
SAFETY AND GENERAL
Use While Driving
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:
et
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.

OPERATIONAL WARNINGS
For Vehicles With An Air Bag
io
1
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
ad
Potentially Explosive Atmospheres
!
w
.m
yr
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
://
w
w
areas such as below decks on boats, fuel or chemical transfer or storage facilities,
areas where the air contains chemicals or particles, such as grain, dust or metal powders, and any other area where you would normally be advised to turn off your vehicle engine. Areas with potentially explosive atmospheres are often but not always
posted.
ht
tp
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.

Error Codes
Error Code
68
.n
et
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. Radio emits only “bonk” (300
Hz) tone if it fails the self-test.
Explanation
Corrective Action
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.

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/OFFcontrol as UNSWB+. When the radio is turned on,
MECH_SWB+ (ON/OFF volume control) will trigger the electronic ON/OFFcontrol(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.

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.
et
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 Li (Lithium) Ion 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 Li (Lithium) Ion battery.

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.

4.1.1 Power Amplifier
The power amplifier consists of two devices:
1. 9Z67 LDMOS driver IC (U3501) and
2. PRF1507 LDMOS PA (Q3501).
ht
tp
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
5A-5
4.1.2 Antenna Switch
The antenna switch circuit consists of two PIN diodes (D3521 and D3551), a pi network (C3531,
L3551 and C3550), and two 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.
4.1.3 Harmonic Filter
.n
et
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.
68
4.1.4 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.

4.1.5 Power Control Integrated Circuit (PCIC)
yr
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.
w
.m
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 to VHF Receiver Front End Schematic Diagram on page 5A-22, VHF Receiver Back End
Schematic Diagram on page 5A-23, and VHF Transmitter Schematic Diagram on page 5A-26)
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.
ht
tp
5.1
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
5A-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.
Receiver Back-End
et
(Refer to VHF Receiver Back End Schematic Diagram on page 5A-23)
68
.n
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.
ad
io
1
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).
w
.m
yr
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.
://
w
w
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.

Automatic Gain Control Circuit
(Refer to VHF Receiver Front End Schematic Diagram on page 5A-22 and VHF Receiver Back End
Schematic Diagram on page 5A-23)
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 back end 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.
et
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.
io
1
68
.n
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.
://
w
w
w
.m
yr
ad
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.

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 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

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

4.1.1 Power Amplifier
The power amplifier consists of two devices:
1. 9Z67 LDMOS driver IC (U101) and
2. PRF1507 LDMOS PA (Q110).
ht
tp
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
5B-5
4.1.2 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.
4.1.3 Harmonic Filter
68
.n
et
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.
4.1.4 Antenna Matching Network
io
1
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.
ad
4.1.5 Power Control Integrated Circuit (PCIC)
yr
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.
w
.m
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.
://
w
w
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.
ht
tp
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 5B-21 and UHF Transmitter
Schematic Diagram on page 5B-25)
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.
ht
tp
5.1
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
5B-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.
Receiver Back-End
(Refer to UHF Receiver Back End Schematic Diagram on page 5B-22)
.n
et
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.
io
1
68
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).
yr
ad
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.
w
.m
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.
://
w
w
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.

Automatic Gain Control Circuit
(Refer to UHF Receiver Front End Schematic Diagram on page 5B-21)
et
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 back end 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.
.n
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.

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.
w

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.
ht
tp
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.
5B-10

Frequency Generation Circuitry
Synthesizer
(Refer to UHF Synthesizer Schematic Diagram on page 5B-23)
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 .
.n
et
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 .

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.

receive oscillator and the receive buffer of U241. The RF signal at U241 pin 8 is run through a

5. Power Control Integrated Circuit (PCIC).
4.1.1 Power Amplifier
The power amplifier consists of two devices:
1. 9Z67 LDMOS driver IC (U101) and
2. PRF1507 LDMOS PA (Q110).
ht
tp
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.
Transmitter
5C-5
4.1.2 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.
4.1.3 Harmonic Filter
68
.n
et
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.
4.1.4 Antenna Matching Network
io
1
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.
ad
4.1.5 Power Control Integrated Circuit (PCIC)
yr
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.
w
.m
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.
://
w
w
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.
ht
tp
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 Band 2 Receiver Front End Schematic Diagram on page 5C-22 and UHF Band 2
Transmitter Schematic Diagram on page 5C-26)
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.
ht
tp
5.1
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
5C-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.
Receiver Back-End
(Refer to UHF Band 2 Receiver Back End Schematic Diagram on page 5C-23)
.n
et
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.
io
1
68
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).
yr
ad
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.
w
.m
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.
://
w
w
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.

Automatic Gain Control Circuit
(Refer to UHF Band 2 Receiver Front End Schematic Diagram on page 5C-22)
et
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 back end 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.
.n
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.

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.
w
.m
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.
://
w
w
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.
ht
tp
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.

Synthesizer
(Refer to UHF Band 2 Synthesizer Schematic Diagram on page 5C-24)
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 .
.n
et
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 5-5: 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.
5C-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 5-1.

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 5C-22).

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.

5. Power Control Integrated Circuit (PCIC).
4.1.1 Power Amplifier
The power amplifier consists of two devices:
1. 9Z67 LDMOS driver IC (U101) and
2. PRF1507 LDMOS PA (Q110).
ht
tp
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
5D-5
4.1.2 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.
4.1.3 Harmonic Filter
68
.n
et
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.
4.1.4 Antenna Matching Network
io
1
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.
ad
4.1.5 Power Control Integrated Circuit (PCIC)
yr
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.
w
.m
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.
://
w
w
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.
ht
tp
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 5D-22 and 330-400MHz
Transmitter Schematic Diagram on page 5D-26)
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.
ht
tp
5.1
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 .
Receiver
5D-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.
Receiver Back-End
(Refer to 330-400MHz Receiver Back End Schematic Diagram on page 5D-23)
.n
et
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.
io
1
68
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).
yr
ad
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.
w
.m
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.
://
w
w
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.

Automatic Gain Control Circuit
(Refer to 330-400MHz Receiver Front End Schematic Diagram on page 5D-22)
et
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 back end 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.
.n
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.

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.
ht
tp
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.

Synthesizer
(Refer to 330-400MHz Synthesizer Schematic Diagram on page 5D-24)
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 .
.n

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 .

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.
