In order to maintain compliance, radios that are FM Approved to intrinsically safe standards MUST be repaired at FM audited service centers. See Further Assistance From Motorola on page 1-2 for more information. Preventive Maintenance Periodic visual inspection and cleaning is recommended. 1.2 Inspection Check that the external surfaces of the radio are clean, and that all external controls and switches are functional. It is not recommended to inspect the interior electronic circuitry. 1.3 Cleaning The following procedures describe the recommended cleaning agents and the methods to be used when cleaning the external and internal surfaces of the radio. External surfaces include the front cover, housing assembly, and battery case. These surfaces should be cleaned whenever a periodic visual inspection reveals the presence of smudges, grease, and/or grime. NOTE Internal surfaces should be cleaned only when the radio is disassembled for servicing or repair. The only recommended agent for cleaning the external radio surfaces is a 0.5% solution of a mild dishwashing detergent in water. The only factory recommended liquid for cleaning the printed circuit boards and their components is isopropyl alcohol (100% by volume). CAUTION: The effects of certain chemicals and their vapors can have harmful results on certain plastics. Aerosol sprays, tuner cleaners, and other chemicals should be avoided. 1. Cleaning External Plastic Surfaces The detergent-water solution should be applied sparingly with a stiff, non-metallic, shortbristled brush to work all loose dirt away from the radio. A soft, absorbent, lintless cloth or tissue should be used to remove the solution and dry the radio. Make sure that no water remains entrapped near the connectors, cracks, or crevices. 1-2 Introduction 2. NOTE 1.4 Cleaning Internal Circuit Boards and Components Isopropyl alcohol may be applied with a stiff, non-metallic, short-bristled brush to dislodge embedded or caked materials located in hard-to-reach areas. The brush stroke should direct the dislodged material out and away from the inside of the radio. Make sure that controls or tunable components are not soaked with alcohol. Do not use high-pressure air to hasten the drying process since this could cause the liquid to collect in unwanted places. Upon completion of the cleaning process, use a soft, absorbent, lintless cloth to dry the area. Do not brush or apply any isopropyl alcohol to the frame, front cover, or back cover. Always use a fresh supply of alcohol and a clean container to prevent contamination by dissolved material (from previous usage). Safe Handling of CMOS and LDMOS Complementary metal-oxide semiconductor (CMOS) devices are used in this family of radios. CMOS characteristics make them susceptible to damage by electrostatic or high voltage charges. Damage can be latent, resulting in failures occurring weeks or months later. Therefore, special precautions must be taken to prevent device damage during disassembly, troubleshooting, and repair. Handling precautions are mandatory for CMOS circuits and are especially important in low humidity conditions. DO NOT attempt to disassemble the radio without first referring to the CMOS CAUTION paragraph in the Disassembly and Reassembly section of the manual. 1.5 General Repair Procedures and Techniques NOTE Environmentally Preferred Products (EPP) (refer to the marking on the printed circuit boards - examples shown below) were developed and assembled using environmentally preferred components and solder assembly techniques that meet or exceed compliance to the European Union’s ROHS and WEEE directives (Waste Electrical and Electronic Equipment (WEEE) Directive 2002/96/EC and Restriction of Hazardous Subtances (ROHS) Directive 2002/95/EC). To maintain product compliance and reliability, use only the Motorola specified parts in this manual. For the identification of lead (Pb) free assemblies, all EPP products will carry the EPP Marking, shown below, on the printed circuit board (PCB). This marking provides information to those performing assembly, servicing and recycling operation on this product, adhering to the JEDEC standard #97. The EPP Marking takes the form of a label or marking on the PCB. Introduction 1-3 Any rework or repair on Environmentally Preferred Products must be done using the appropriate lead-free solder wire and solder paste as stated in the following tables: Table 1-1.

If the identical replacement component is not locally available, check the parts list for the proper Motorola part number and order the component from the nearest Motorola Communications parts center listed in the “Piece Parts” section of this manual. Rigid Circuit Boards The family of radios uses bonded, multi-layer, printed circuit boards. Since the inner layers are not accessible, some special considerations are required when soldering and unsoldering components. The through-plated holes may interconnect multiple layers of the printed circuit. Therefore, care should be exercised to avoid pulling the plated circuit out of the hole. When soldering near the connector pins: • Avoid accidentally getting solder in the connector. • Be careful not to form solder bridges between the connector pins • Closely examine your work for shorts due to solder bridges.

Radio Memory Requirements Reference No. U101 U104 4.3.1 Description Microprocessor Serial EEPROM Size Flash ROM 128 Kbyte * 8 RAM 5 Kbyte * 8 8 Kbit * 8 Memory Usage Radio operation is controlled by software that is stored in internal Flash ROM memory. Radio parameters and customer specific information is stored in External EEPROM (U104). The operating status of the radio is maintained in RAM located within the microprocessor. When the radio is turned off, the operating status of the radio is written to EEPROM before operating voltage is removed from the microprocessor. 4.3.2 Control and Indicator Interface Ports Pin 35 and 36 are outputs which control the Sub-PCB mounted LED indicator. When Pin 35 is high, the indicator is green. When Pin 36 is high, the indicator is red. When both are high, the indicator is amber. When both are low, the indicator id is off. Pressing the side-mounted PTT button (PB501) provides a low to port Pin 44, which indicates PTT is asserted.

Chapter 5 435 – 480 MHz UHF2 Theory Of Operation 5.1 Introduction This chapter provides a detailed theory of operation for the radio components. Schematic diagrams for the circuits described in the following paragraphs are located in Chapter 7 of this manual. 5.2 UHF2 Receiver The UHF2 receiver design covers the frequency range of 435 – 480 MHz and it is a double conversion super heterodyne with 1st IF 45.1 MHz and 2nd IF 455 kHz. The receiver is divided into two major blocks, Front End and Back End as shown in Figure 5-1. Preselector Filter RF Amp Postselector Crystal IF 1st Mixer Filter Amp Filter RX from Antenna Switch Inj Filter First LO from Synthesizer N/S_SW Descriminator 455C24 LPF Recovered Audio Quadrature Detector Ceramic Filter 455FW 455HW IF Amp RSSI Crystal 44.645MHz Figure 5-1. UHF2 Receiver Block Diagram 5-2 5.2.1 435 – 480 MHz UHF2 Theory Of Operation: UHF2 Receiver Receiver Front End Incoming RF signals from antenna are first routed through the harmonic filter (L409, L410, L411, C426, C427, C428, C429, C445, C446) and antenna switch (CR301), part of the transmitter circuitry, before being applied to the receiver front end. The receiver front end consists of preselector filter, RF amplifier, post-selector filter and a single-balanced mixer. The preselector filter is a varactor-tuned 2-pole design using discrete elements (L320, L324, C351, C352, C353, C354, C355, C356, C357, C358, C359, C360, C361) in a series/shunt resonator configuration. It is a band-shift filter and the frequency shift is controlled by varactor diodes CR314 and CR307, which are connected to the microprocessor. It is configured to provide steeper attenuation above the passband for improved spurious rejection when low-side local injection is used. The frequency is separated into 8 steps and controlled by CPU (435 – 480 MHz). The output of this filter is matched to the base of RF amplifier Q301 which provides 13dB of gain. The output of the RF amplifier is applied to the post-selector filter. The post-selector filter designed using discrete elements (L322, L323, L328, C379, C354, C355) in a series/shunt resonator configuration. It is a band-shift filter and the frequency shift is controlled by varactor diodes CR313, CR304 and CR305, which are connected to the microprocessor. It is configured to provide steeper attenuation above the passband for improved spurious rejection when low-side local injection is used. The frequency is separated into 8 steps and controlled by CPU (435 – 480 MHz). The output of the post selector is connected to the single-balanced mixer consisting of components L329, L333, Q306 and Q307. 1st local signal generated from VCO is filtered by injection filter (L310, L331, C325, C326, C327) to remove second harmonics. The converted 1st IF frequency at mixer passes through L331 and matches the 45.1 MHz IF signal to pair crystal filter (FL301). 5.2.2 Receiver Back End The 1st IF signal is amplified about 15 dB by IF amp Q303. The output of the IF amp is connected to IF IC (U201). 1st IF frequency (45.1 MHz) and 2nd LO frequency (44.645 MHz) are mixed in U201. The second mixer converts the 45.1 MHz high IF frequency to 2nd IF frequency (455 kHz). Additional IF selectivity is provided by two ceramic filters (CF1, CF2). The wider filter 455 FW is used for 25 kHz channel spacing, and the narrower filter 455 HW is used for 12.5 kHz channel spacing. These two ceramic filters may eliminate undesired signal and demodulated by demodulator in U201. N/S_SW which connected to microprocessor is used to select the wide and narrow band. The mute (squelch) circuit switches off the audio amplifier when no audio is present. The squelch circuit consists of U201 and U202 and their associated components. The noise signal from Pin 9 of U201 is used to control the squelch circuit sensitivity of U202. The noise passes through filter, and is amplified by internal amp of U201. The amplified noise act as a DC voltage to control the mute system. So if the noise level is under the threshold voltage, the microprocessor (U101) un-mutes the radio. If the noise level is over the threshold voltage, the microprocessor mutes the radio. The squelch level is tuned in the factory. When a component or a part in the RX system is replaced, the squelch must be re-tuned using the Tuner. 435 – 480 MHz UHF2 Theory Of Operation: UHF2 Transmitter 5.3 5-3 UHF2 Transmitter The UHF2 transmitter covers the range of 435 – 480 MHz. Depending on model, the output power of the transmitter is switchable on a per-channel basis between high power (4 Watts) and low power (1 Watt). The transmitter is divided into four major blocks as shown in Figure 5-2. • • • • Power Amplifier Harmonic Filter Antenna Matching Network Power Control. SWB+ BAT+ Power Control Current Detect CR401 From VCO Attenuator Circuit Antenna Strip Line Pre Driver Amp Driver Amp Final Amp Harmonic Filter To Receiver Antenna Switch Figure 5-2. UHF2 Transmitter Block Diagram 5.3.1 Power Amplifier The transmitter power amplifier has three stages of amplification – Pre Driver (Q401), Driver Amp (Q402) and Final Amp (Q403). Signal from TX VCO is applied to the pre driver via an attenuator circuit. The attenuator is pie style resistor attenuator, and is used as isolation between VCO and the power amps. The -4dBm TX RF signal from attenuator is then amplified by pre driver and driver amp to around +25dBm and is applied to the final amp. The final amp (Q403) is an enhancement-mode N-channel MOSFET device providing a gain of 12dB. The device drain current is drawn directly from the DC battery supply voltage input via L413. A matching network consisting of C416 to C420 and a strip line, transforms the impedance to approximately 50 Ohm. 5.3.2 Antenna Switch An antenna switch works mainly as a switching device between transmit and receive paths. In transmit mode (PTT), Q407 is turned on and both PIN diodes (CR401, CR301) are forward biased into conduction. This enables the RF signal to pass to the harmonic filter and then to the antenna. In the receiver mode, both diodes are off. Signals applied to the antenna jack are routed via the LPF (harmonic filter), through network L409 to L411, to the receiver input. 5.3.3 Harmonic Filter The harmonic filter consists of components L409, L410, L411, C426, C427, C428, C429, C430, C445 and C446. The harmonic filter is a seven-pole Chebychev filter. 5-4 5.3.4 435 – 480 MHz UHF2 Theory Of Operation: UHF2 Frequency Generation Circuitry Auto Power Control The APC keeps the current supply constant to the final amp (Q403). The drain current of Q403 (final amp) is sensed across resistor R417. The voltage difference across R417 is amplified through U401 by the ratio of R423 to R417. The differential signal at the output of U401 (Pin 7) is passed to Q404 and Q405 that produces a constant power output to the antenna. If the current is changed due to change of battery voltage or load, APC controls gate voltage of Q403 and collector voltage of Q401 and drain voltage of Q402 to keep TX power stable. This circuit stabilizes TX power at a pre-determined level adjusted by U402. This bias voltage is tuned in the factory. If the transistor (Q403) is replaced, the RF Output Power must be tuned. By tuning the RF output power, the bias voltage will be tuned through U402. Extra care has to be taken during the tuning process. Do not exceed the maximum allowed bias voltage. 5.4 UHF2 Frequency Generation Circuitry The PLL synthesizer subsystem consists of the reference oscillator (VCTCXO), VCO, PLL IC, Charge Pump and Loop Filter.

The reference frequency 12.8 MHz VCTCXO (Voltage Controlled Temperature Compensated Crystal Oscillator) is applied to the PLL IC (U701) via Pin 1. Main frequency can be adjusted by chip trimmer of VCTCXO. This frequency provides reference to the PLL IC and has a frequency stability of +/-2.5PPM (max) at the temperature ranging from -30 to +60 Degree Celsius. 435 – 480 MHz UHF2 Theory Of Operation: UHF2 Frequency Generation Circuitry 5.4.2 5-5 PLL IC Prescaler and Comparator The reference frequency from VCTCXO is divided to 6.25 kHz or 5 kHz by reference counter, R. The RF signal input from the VCO is divided to by prescaler (1/64), divided by N and A counters in PLL IC to determine frequency steps and then supplied to the comparator. The comparison frequency is 6.25/5 kHz. The internal phase comparator compares the phase difference between the reference and VCO signal. When the phase of the reference frequency is leading, Pin15 (R) is the output. When VCO frequency is leading, Pin 16 (P) is the output. When P=R, small pulses are the output of the phase detector. 5.4.3 Voltage Doubler and Charge Pump The voltage doubler (U507) converts 5V to 10V and is applied to the charge pump circuitry. The charge pump is used for charging output signals P, R supplied by PLL IC from 0-3.3V to 0-10V. This voltage is used to drive the VCO. 5.4.4 Loop Filter The loop filter contains C751, C752, C753, C754, R726, R727, R728. It reduces the residual sideband noise to get the best signal-to-noise ratio. The output signal from loop filter is applied to VCO. 5.4.5 Dual VCO The dual VCO module contains a RX VCO and a TX VCO. They are configured as colpitts oscillators and connected to power up through transistor switches. Only one VCO is selected at a time. A steering line voltage between 0.35V and 9.7V at varactor CR701 tunes the full RX frequency range from 389.9MHz to 434.9MHz, and varactor CR702 tunes the full TX frequency range from 435MHz to 480MHz. In Receiver mode, high signal of RX_EN from Pin 71, U101 activates Q305. When Q305 is activated, current flows through the base of Q304 and thus activates the Q705. The varactor CR701 sets the resonance frequency. When there is a change in voltage supplied by loop filter, there is a change in the resonance frequency. L703 is the resonating coil, which forms the tank circuit together with variable cap C710. In Transmit mode, high signal of TX_EN1 from Pin 84, U101 enables current flows through collector of Q503 and thus activates Q706. The varactor CR702 sets the resonance frequency. When there is a change in voltage supplied by loop filter, there is a change in the resonance frequency. L706 is the resonating tuning coil, which forms the tank circuit together with variable cap C722. 5-6 Keypad Left, Right and P1 to P3 keys are directly connected to microprocessor via 22 pin connector.

Schematic diagrams for the circuits described in the following paragraphs are located in Chapter 10 of this manual. 8.2 VHF Receiver The VHF receiver design covers the frequency range of 136 – 174 MHz and it is a double conversion super heterodyne with 1st IF 45.1 MHz and 2nd IF 455 kHz. The receiver is divided into two major blocks, Front End and Back End as shown in Figure 8-1. Preselector Filter RF Amp Postselector Crystal IF 1st Mixer Filter Amp Filter RX from Antenna Switch Inj Filter First LO from Synthesizer N/S_SW Descriminator 455C24 LPF Recovered Audio Quadrature Detector Ceramic Filter 455FW 455HW IF Amp RSSI Crystal 44.645MHz Figure 8-1. VHF Receiver Block Diagram 8-2 8.2.1 136 – 174 MHz VHF Theory Of Operation: VHF Receiver Receiver Front End Incoming RF signals from antenna are first routed through the harmonic filter (L409, L410, L411, C426, C427, C428, C429, C445, C446) and antenna switch (CR301), part of the transmitter circuitry, before being applied to the receiver front end. The receiver front end consists of preselector filter, RF amplifier, post-selector filter and a single-balanced mixer. The preselector filter is a varactor-tuned 2-pole design using discrete elements (L301, L302, L303, L304, C301, C304, C305, C307) in a shunt or series resonator configuration. It is a band-shift filter and the frequency shift is controlled by varactor diodes CR302 and CR303, which are connected to the microprocessor. It is configured to provide steeper attenuation above the passband for improved spurious rejection when high-side local injection is used. The frequency is separated into 6 steps and controlled by CPU (136 – 174 MHz). The output of this filter is matched to the base of RF amplifier Q301 which provides 15dB of gain. The output of the RF amplifier is applied to the post-selector filter. The post-selector filter designed using discrete elements (L307, L308, L309, L311, C315 and C354) in a series/shunt resonator configuration. It is a band-shift filter and the frequency shift is controlled by varactor diodes CR305 and CR307, which are connected to the microprocessor. It is configured to provide steeper attenuation above the passband for improved spurious rejection when low-side local injection is used. The frequency is separated into 6 steps and controlled by CPU (136 – 174 MHz). The output of the post selector is connected to the single-balanced mixer consisting of components L329, L333, Q306 and Q307. 1st local signal generated from VCO is filtered by injection filter (L310, L331, C325, C326, C327, C333 and C365) to remove second harmonics. The converted 1st IF frequency at mixer passes through L331 and matches the 45.1 MHz IF signal to pair crystal filter (FL301). 8.2.2 Receiver Back End The 1st IF signal is amplified about 15 dB by IF amp Q303. The output of the IF amp is connected to IF IC (U201). 1st IF frequency (45.1 MHz) and 2nd LO frequency (44.645 MHz) are mixed in U201. The second mixer converts the 45.1 MHz high IF frequency to 2nd IF frequency (455 kHz). Additional IF selectivity is provided by two ceramic filters (CF1, CF2). The wider filter 455 FW is used for 25 kHz channel spacing, and the narrower filter 455 HW is used for 12.5 kHz channel spacing. These two ceramic filters may eliminate undesired signal and demodulated by demodulator in U201. N/S_SW which connected to microprocessor is used to select the wide and narrow band. The mute (squelch) circuit switches off the audio amplifier when no audio is present. The squelch circuit consists of U201 and U202 and their associated components. The noise signal from pin 9 of U201 is used to control the squelch circuit sensitivity of U202. The noise passes through filter, and is amplified by internal amp of U201. The amplified noise act as a DC voltage to control the mute system. So if the noise level is under the threshold voltage, the microprocessor (U101) un-mutes the radio. If the noise level is over the threshold voltage, the microprocessor mutes the radio. The squelch level is tuned in the factory. When a component or a part in the RX system is replaced, the squelch must be re-tuned using the Tuner. 136 – 174 MHz VHF Theory Of Operation: VHF Transmitter 8.3 8-3 VHF Transmitter The VHF transmitter covers the range of 136 – 174 MHz. Depending on model, the output power of the transmitter is switchable on a per-channel basis between high power (5 Watts) and low power (1 Watt). The transmitter is divided into four major blocks as shown in Figure 8-2. • Power Amplifier • Harmonic Filter • Power Control SWB+ BAT+ Power Control Current Detect CR401 From VCO Attenuator Circuit Antenna Strip Line Pre Driver Amp Driver Amp Final Amp Harmonic Filter To Receiver Antenna Switch Figure 8-2. VHF Transmitter Block Diagram 8.3.1 Power Amplifier The transmitter power amplifier has three stages of amplification – Pre Driver (Q401), Driver Amp (Q402) and Final Amp (Q403). Signal from TX VCO is applied to the pre driver via an attenuator circuit. The attenuator is pie style resistor attenuator, and is used as isolation between VCO and the power amps. The -3dBm TX RF signal from attenuator is then amplified by pre driver and driver amp to around +28dBm and is applied to the final amp. The final amp (Q403) is an enhancement-mode N-channel MOSFET device providing a gain of 12dB. The device drain current is drawn directly from the DC battery supply voltage input via L413. A matching network consisting of C417, C418, C419, C420, C455 and a strip line, transforms the impedance to approximately 50 Ohm. 8.3.2 Antenna Switch An antenna switch works mainly as a switching device between transmit and receive paths. In transmit mode (PTT), Q407 is turned on and both PIN diodes (CR401, CR301) are forward biased into conduction. This enables the RF signal to pass to the harmonic filter and then to the antenna. In the receiver mode, both diodes are off. Signals applied to the antenna jack are routed via the LPF (harmonic filter), through a TX Low Pass Filter (L409, L410, L411, C426, C427, C428, C429, C430, C445 and C446), to the receiver input. 8.3.3 Harmonic Filter The harmonic filter consists of components L409, L410, L411, C426, C427, C428, C429, C430, C445 and C446. The harmonic filter is a seven-pole Chebychev filter. 8-4 8.3.4 136 – 174 MHz VHF Theory Of Operation: VHF Frequency Generation Circuitry Auto Power Control The APC keeps the current supply constant to the final amp (Q403). The drain current of Q403 (final amp) is sensed across resistor R417. The voltage difference across R417. The differential signal at the output of U401 (pin 7) is passed to Q404 and Q405 that produces a constant power output to the antenna. If the current is changed due to change of battery voltage or load, APC controls gate voltage of Q403 and collector voltage of Q401 and drain voltage of Q402 to keep TX power stable. This circuit stabilizes TX power at a pre-determined level adjusted by U402. This bias voltage is tuned in the factory. If the transistor (Q403) is replaced, the RF Output Power must be tuned. By tuning the RF output power, the bias voltage will be tuned through U402. Extra care has to be taken during the tuning process. Do not exceed the maximum allowed bias voltage. 8.4 VHF Frequency Generation Circuitry The PLL synthesizer subsystem consists of the reference oscillator (VCTCXO), VCO, PLL IC, Charge Pump and Loop Filter. TX VCO Circuit FL701 Modulating Signal TX Out Synthesizer U701 Charge Pump Loop Filter 12.8MHz Ref.OSC. PLL Data from μP To PA Driver Voltage Doubler RX Out RX VCO Circuit To Mixer Figure 8-3. VHF Frequency Generation Unit Block Diagram 8.4.1 Reference Oscillator (12.8 MHz VCTCXO) The reference oscillator is powered by regulated 5V provided by U505. The reference frequency 12.8 MHz VCTCXO (Voltage Controlled Temperature Compensated Crystal Oscillator) is applied to the PLL IC (U701) via pin 1. Main frequency can be adjusted by chip trimmer of VCTCXO. This frequency provides reference to the PLL IC and has a frequency stability of +/-2.5PPM (max) at the temperature ranging from -30 to +60 Degree Celsius. 136 – 174 MHz VHF Theory Of Operation: VHF Frequency Generation Circuitry 8.4.2 8-5 PLL IC Prescaler and Comparator The reference frequency from VCTCXO is divided to 6.25 kHz or 5 kHz by reference counter, R. The RF signal input from the VCO is divided to by prescaler (1/64), divided by N and A counters in PLL IC to determine frequency steps and then supplied to the comparator. The comparison frequency is 6.25/5 kHz. The internal phase comparator compares the phase difference between the reference and VCO signal. When the phase of the reference frequency is leading, Pin15 (R) is the output. When VCO frequency is leading, Pin16 (P) is the output. When P=R, small pulses are the output of the phase detector. 8.4.3 Voltage Doubler and Charge Pump The voltage doubler (U507) converts 5V to 10V and is applied to the charge pump circuitry. The charge pump is used for charging output signals P, R supplied by PLL IC from 0-3.3V to 0-10V. This voltage is used to drive the VCO. 8.4.4 Loop Filter The loop filter contains C751, C752, C753, C754, R726, R727, R728. It reduces the residual sideband noise to get the best signal-to-noise ratio. The output signal from loop filter is applied to VCO. 8.4.5 Dual VCO The dual VCO module contains a RX VCO and a TX VCO. They are configured as colpitts oscillators and connected to power up through transistor switches. Only one VCO is selected at a time. A steering line voltage between 0.35V and 9.7V at varactor CR701 tunes the full RX frequency range from 181.1 MHz to 219.1 MHz, and varactor CR703 tunes the full TX frequency range from 136 MHz to 174 MHz. In Receiver mode, high signal of RX_EN from pin 71, U101 activates Q305. When Q305 is activated, current flows through the base of Q304 and thus activates the Q705. The varactor CR701 sets the resonance frequency. When there is a change in voltage supplied by loop filter, there is a change in the resonance frequency. L703 is the resonating coil, which forms the tank circuit together with variable cap C710. In Transmit mode, high signal of TX_EN1 from pin 84, U101 enables current flows through collector of Q503 and thus activates Q706. The varactor CR703 sets the resonance frequency. When there is a change in voltage supplied by loop filter, there is a change in the resonance frequency. L706 is the resonating tuning coil, which forms the tank circuit together with variable cap C722. 8-6 Keypad Left, Right and P1 to P3 keys are directly connected to microprocessor via 22 pin connector.

Schematic diagrams for the circuits described in the following paragraphs are located in Chapter 14 of this manual. 11.2 UHF1 Receiver The UHF1 receiver design covers the frequency range of 403 – 447MHz and it is a double conversion super heterodyne with 1st IF 45.1MHz and 2nd IF 455kHz. The receiver is divided into two major blocks, Front End and Back End as shown in Figure 11-1.

UHF1 Receiver Block Diagram 11-2 403 – 447 MHz UHF1 Theory Of Operation: UHF1 Receiver 11.2.1 Receiver Front End Incoming RF signals from antenna are first routed through the harmonic filter (L409 – L411, C426 – C429, C445, C446) and antenna switch (CR301), part of the transmitter circuitry, before being applied to the receiver front end. The receiver front end consists of preselector filter, RF amplifier, postselector filter and a double-balanced mixer. The preselector filter is a varactor-tuned 2-pole design using discrete elements (L320, L324, C351, C361, CR307 and CR314) in series/shunt resonator configuration. It is a band-shift filter and the frequency shift is controlled by varactor diodes CR307 and CR314, which are connected to the microprocessor. It is configured to provide steeper attenuation above the pass band for improved spurious rejection when high-side local injection is used. The frequency is separated into 8 steps and controlled by CPU (403 – 447MHz). The output of this filter is matched to the base of RF amplifier Q301 which provides 13dB of gain. The output of the RF amplifier is applied to the post-selector filter. The post-selector filter designed using discrete elements (L323, L328, C379, C363 and C355) in a series/shunt resonator configuration. It is a band-shift filter and the frequency shift is controlled by varactor diodes CR305 and CR313, which are connected to the microprocessor. It is configured to provide steeper attenuation above the passband for improved spurious rejection when high-side local injection is used. The frequency is separated into 8 steps and controlled by CPU (403 – 447MHz). The output of the post selector is connected to the double-balanced mixer consisting of components L329, L333, CR316. 1st local signal generated from VCO is filtered by injection filter (L310, L331, C325, C326, C388, C386, C365 and C387) to remove harmonics. The converted 1st IF frequency at mixer passes through L333 and matches the 45.1MHz IF signal to crystal filter (FL301). 11.2.2 Receiver Back End The 1st IF signal is amplified about 15dB by IF amp Q303. The output of the IF amp is connected to IF IC (U201). 1st IF frequency (45.1MHz) and 2nd LO frequency (44.645MHz) are mixed in U201. The second mixer converts the 45.1MHz high IF frequency to 2nd IF frequency (455kHz). Additional IF selectivity is provided by two ceramic filters (CF1, CF2). The wider filter 455FW is used for 25kHz channel spacing, and the narrower filter 455HW is used for 12.5kHz channel spacing. These two ceramic filters may eliminate undesired signal and demodulated by demodulator in U201. N/S_SW which connected to microprocessor is used to select the side and narrow band. The mute (squelch) circuit switches off the audio amplifier when no audio is present. The squelch circuit consists of U201 and U202 and their associated components. The noise signal from Pin 9 of U201 is used to control the squelch circuit sensitivity of U202. The noise passes through filter, and is amplified by internal amp of U201. The amplified noise acts as a DC voltage to control the mute system. So if the noise level is under the threshold voltage, the microprocessor (U101) un-mutes the radio. If the noise level is over the threshold voltage, the microprocessor mutes the radio. The squelch level is tuned in the factory. When a component or a part in the RX system is replaced, the squelch must be re-tuned using the Tuner. 403 – 447 MHz UHF1 Theory Of Operation: UHF1 Transmitter 11-3 11.3 UHF1 Transmitter The UHF1 transmitter covers the range of 403 – 447MHz. Depending on model, the output power of the transmitter is switchable on a per-channel basis between high power (4 Watt) and low power (1 Watt). The transmitter is divided into four major blocks as shown in Figure 11-2. • • • • Power Amplifier Harmonic Filter Antenna Matching Network Power Control. SWB+ BAT+ Power Control Current Detect CR401 From VCO Attenuator Circuit Antenna Strip Line Pre Driver Amp Driver Amp Final Amp Harmonic Filter To Receiver Antenna Switch Figure 11-2. UHF1 Transmitter Block Diagram 11.3.1 Power Amplifier The transmitter power amplifier has three stages of amplification – Pre Driver (Q401), Driver Amp (Q402) and Final Amp (Q403). Signal from TX VCO is applied to the pre driver via an attenuator circuit. The attenuator is pie style resistor attenuator, and is used as isolation between VCO and the power amps. The -4dBm TX RF signal from attenuator is then amplified by pre driver and driver amp to around +25dBm and is applied to the final amp. The final amp (Q403) is an enhancement-mode N-channel MOSFET device providing a gain of 12dB. The device drain current is drawn directly from the DC battery supply voltage input via L413. A matching network consisting of C416, C417, C418, C419, C420, C451, C422, C452 and a strip line, transforms the impedance to approximately 50Ohm. 11.3.2 Antenna Switch An antenna switch works mainly as a switching device between transmit and receive paths. In transmit mode (PTT), Q407 is turned on and both PIN diodes (CR401, CR301) are forward biased into conduction. This enables the RF signal to pass to the harmonic filter and then to the antenna. In the receiver mode, both diodes are off. Signals applied to the antenna jack are routed via the LPF (harmonic filter), through network L409, L410, L411, C426, C427, C428, C429, C430, C445, C446 to the receiver input. 11.3.3 Harmonic Filter The harmonic filter consists of components L409, L410, L411, C426, C427, C428, C429, C430, C445 and C446. The harmonic filter is a seven-pole Chebychev filter. 11-4 403 – 447 MHz UHF1 Theory Of Operation: UHF1 Frequency Generation Circuitry 11.3.4 Auto Power Control The APC keeps the current supply constant to the final amp (Q403). The drain current of Q403 (final amp) is sensed across resistor R417. The differential signal at the output of U401 (Pin 7) is passed to Q404 and Q405 that produces a constant power output to the antenna. If the current is changed due to change of battery voltage or load, APC controls gate voltage of Q403 and collector voltage of Q401 and drain voltage of Q402 to keep TX power stable. This circuit stabilizes TX power at a predetermined level adjusted by U402. This bias voltage is tuned in the factory. If the transistor (Q403) is replaced, the RF Output Power must be tuned. By tuning the RF output power, the bias voltage will be tuned through U402. Extra care has to be taken during the tuning process. Do not exceed the maximum allowed bias voltage. 11.4 UHF1 Frequency Generation Circuitry The PLL synthesizer subsystem consists of the reference oscillator (VCTCXO), VCO, PLLIC, Charge pump and Loop Filter. TX VCO Circuit FL701 Modulating Signal TX Out Synthesizer U701 Charge Pump Loop Filter 12.8MHz Ref.OSC. PLL Data from μP To PA Driver Voltage Doubler RX Out RX VCO Circuit To Mixer Figure 11-3. UHF1 Frequency Generation Unit Block Diagram 11.4.1 Reference Oscillator (12.8 MHz VCTCXO) The reference oscillator is powered by regulated 5V provided by U505. The reference frequency 12.8MHz VCTCXO (Voltage Controlled Temperature Compensated Crystal Oscillator) is applied to the PLL IC (U701) via Pin 1. Min frequency can be adjusted by chip trimmer of VCTCXO. This frequency provides reference to the PLL IC and has a frequency stability of +/-2.5PPM (max) at the temperature ranging from -30 to +60 Degree Celsius. 403 – 447 MHz UHF1 Theory Of Operation: UHF1 Frequency Generation Circuitry 11-5 11.4.2 PLL IC Prescaler and Comparator The reference frequency from VCTCXO is divided to 6.25kHz or 5kHz by reference counter, R. The RF signal input from the VCO is divided to by prescaler (1/64), divided by N and A counters in PLL IC to determine frequency steps and then supplied to the comparator. The comparison frequency is 6.25/5kHz. The internal phase comparator compares the phase difference between the reference and VCO signal. When the phase of the reference frequency is leading, Pin 15(R) is the output. When VCO frequency is leading, Pin 16 (P) is the output. When P=R, small pulses are the output of the phase detector. 11.4.3 Voltage Doubler and Charge Pump The voltage doubler (U507) converts 5V to 10V and is applied to the charge pump circuitry. The charge pump is used for charging output signals P, R supplied by PLL IC from 0-3.3v to 0-10v. This voltage is used to drive the VCO. 11.4.4 Loop Filter The loop filter contains C751 – C754, R726 – R728. It reduces the residual side-band noise to get the best signal-to noise ratio. The output signal from loop filter is applied to VCO. 11.4.5 Dual VCO The dual VCO module contains a RX VCO and a TX VCO. They are configured as colpitts oscillators and connected to power up through transistor switches. Only one VCO is selected at a time. A steering line voltage between 0.35V and 9.7V at varactor CR701 tunes the fill RX frequency range from 357.9MHz to 401.9MHz and varactor CR703 tunes the full TX frequency range from 403MHz to 447MHz. In Receiver mode, high signal of RX_EN from Pin 71, U101 activates Q305. When Q305 is activated, current flows through the base of Q304 and thus activates the Q705. The varactor CR701 sets the resonance frequency. When there is a change in voltage supplied by loop filter, there is a change in the resonance frequency. L703 is the resonating coil, which forms the tank circuit together with variable cap C710. In Transmit mode, high signal of TX_EN1 from Pin 84, U101 enables current flows through collector of Q503 and thus activates Q706. The varactor CR703 sets the resonance frequency. When there is a change in voltage supplied by loop filter, there is a change in the resonance frequency. L706 is the resonating tuning coil, which forms the tank circuit together with variable cap C722. 11-6 403 – 447 MHz UHF1 Theory Of Operation: Keypad 11.5 Keypad Left, Right and P1 to P3 keys are directly connected to microprocessor via 22 Pin connector.
