Introduction 2-1 Chapter 2 Theory of Operation 2.1 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 4 of this manual. 2.2 Radio Power Distribution A block diagram of the DC power distribution throughout the radio board is shown in Figure 2-1.

Keypad Keypad The keypad block diagram is shown in Figure 2-2. The comparator compares the voltage when any one of the keypad row or keypad column keys is pressed. Pressing a key sends a message to the microprocessor through the output (KEY_INT) line signifying that a key has been pressed. The microprocessor then samples the Analog to Digital voltages at the keypad row and keypad column, and makes a comparison with a map table to identify the key pressed. Keypad Column Data 9 pin connector 2.
2-4 2.4 Controller Controller The controller board is the central interface between the various subsystems of the radio. It is separated into MCU digital and audio/signalling functions as shown in Figure 2-3.

UHF Transmitter 2.5 2-5 UHF Transmitter The UHF transmitter consists of the following basic circuits as shown in Figure 2-4. • • • • Power amplifier (PA) Antenna switch/harmonic filter Antenna matching network Power control integrated circuit (PCIC) PCIC From VCO Antenna Jack Vcontrol Vcontrol PA Driver PA-Final Stage Antenna Switch/ Matching Network/ Harmonic Filter Figure 2-4. UHF Transmitter Block Diagram 2.5.1 Power Amplifier (PA) The PA consists of two LDMOS devices: 1. PA driver, U101 2.
2-6 UHF Transmitter 2.5.3 Harmonic Filter The harmonic filter consists of C104, L102, C143, C103, L101, C142 and C102. The harmonic filter for UHF is a modified Zolotarev design 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. 2.5.
UHF Receiver 2.6 2-7 UHF Receiver The UHF receiver consists of front end, back end, and automatic gain control circuits. A block diagram of the receiver is shown in Figure 2-5. Detailed descriptions of these stages are contained in the paragraphs that follow.
2-8 UHF Receiver The output of the post-RF amplifier filter is connected to the passive double balanced mixer consisting of components T301, T302, and CR306. Matching of the filter to the mixer is provided by C381. After mixing with the first local oscillator (LO) signal from the voltage controlled oscillator (VCO) using low side injection, the RF signal is down-converted to a 45.1 MHz IF signal.
Synthesizer 2-9 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. 2.6.4 Frequency Generation Circuit The frequency generation circuit, shown in Figure2-6, is composed of Fractional-N synthesizer U201 and VCO/Buffer IC U241.
2-10 Voltage Controlled Oscillator (VCO) To achieve fast locking for the synthesizer, an internal adapt charge pump provides higher current at pin 45 of U201 to put the synthesizer within the lock range. The required frequency is then locked by normal mode charge pump at U201, pin 43. Both the normal and adapt charge pumps get their supply from the capacitive voltage multiplier made up of C258, C259, C228, triple diode CR201 and level shifters U210 and U211. Two 3.
Voltage Controlled Oscillator (VCO) 2-11 The operation logic is shown in Table 2-2.
2-12 VHF Transmitter U241-10 is injected into the input of the PA module (U101-16). Also in transmit mode, the audio signal to be frequency modulated onto the carrier is received through U201-41. When a high impedance is applied to U241-19, the VCO operates in battery saver mode. In this mode, both the receive and transmit oscillators, as well as the receive transmit and prescaler buffer, are turned off. 2.
VHF Transmitter 2-13 the shunt diode to a high impedance at the input of the harmonic filter. In the receive mode, the diodes are both off, creating a low attenuation path between the antenna and receiver ports. 2.9.3 Harmonic Filter The harmonic filter consists of C3532 to C3536, L3531 and L3532. This network forms a low-pass filter to attenuate harmonic energy of the transmitter to specifications level. The harmonic filter insertion loss is typically less than 1.2dB. 2.9.
2-14 VHF Receiver 2.10 VHF Receiver The VHF receiver consists of front end, back end, and automatic gain control circuits. A block diagram of the VHF receiver is shown in Figure 2-10. Detailed descriptions of these features are contained in the paragraphs that follow.
VHF Receiver 2-15 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.
2-16 Synthesizer current gain NPN transistor, is drawn through the PIN diode to turn it on. Maximum current flowing through the pin is limited by resistors R3316, R3313, R3306 and R3324. Feedback capacitor C3326 is used to provide some stability to this high gain stage. An additional gain control circuit is formed by Q3201 and associated components.
Voltage Control Oscillator (VCO) 2-17 In achieving fast locking for the synthesizer, an internal adapt charge pump provides higher current at pin 45 of U3701 to put the synthesizer within lock range. The required frequency is then locked by normal mode charge pump at pin 43. Both the normal and adapt charge pumps get their supply from the capacitive voltage multiplier made up of C3701 to C3704 and triple diodes D3701and D3702. Two 3.
2-18 Voltage Control Oscillator (VCO) at the VCO. This voltage is a DC voltage typically between 3.5V and 9.5V when the PLL is locked on frequency.
Voltage Control Oscillator (VCO) 2-19 During the transmit condition, when PTT is depressed, 3.2 volts is applied to U3801, pin 19. This activates the transmit VCO by enabling the transmit oscillator and the transmit buffer of U3801. The RF signal at U3801, pin 10 is injected into the input of the PA module (U3501, pin16). This RF signal is the TX RF INJECTION. Also in transmit mode, the audio signal to be frequency modulated onto the carrier is received through U3701, pin 41.
2-20 Voltage Control Oscillator (VCO)
Introduction 3-1 Chapter 3 Maintenance 3.1 Introduction This section of the manual describes: • preventive maintenance • safe handling of CMOS devices • repair procedures and techniques 3.2 Preventive Maintenance The radios do not require a scheduled preventive maintenance program; however, periodic visual inspection and cleaning is recommended. 3.2.1 Inspection Check that the external surfaces of the radio are clean, and that all external controls and switches are functional.
3-2 Safe Handling of CMOS and LDMOS NOTE Always use a fresh supply of alcohol and a clean container to prevent contamination by dissolved material (from previous usage). 3.3 Safe Handling of CMOS and LDMOS Complementary metal-oxide semiconductor (CMOS) and lateral diffusion metal oxide semiconductor (LDMOS) devices are used in this family of radios. CMOS characteristics make them susceptible to damage by electrostatic or high voltage charges.
General Repair Procedures and Techniques 3-3 ❏ To remove a chip component: • Use a hot-air hand piece and position the nozzle of the hand piece approximately 1/8" (0.3 cm) above the component to be removed. • Begin applying the hot air. Once the solder reflows, remove the component using a pair of tweezers. • Using a solder wick and a soldering iron or a power desoldering station, remove the excess solder from the pads.

3-6 3.7 Removing and Reinstalling the Circuit Board Removing and Reinstalling the Circuit Board Both the UHF and VHF circuit boards are removed from the radio chassis in the following manner: 1. Refer to the Basic Service Manual (see Section 1 - Related Documents) for radio disassembly, then use a Torx driver and a T-6 bit to remove the four Torx screws shown in Figure 3-2. 2.
Power Up Self-Test Error Codes 3.8 3-7 Power Up Self-Test Error Codes Turning on the radio starts a self-test routine that checks the RAM, ROM checksum, EEPROM hardware and EEPROM checksum. If these checks are successful, the radio generates two highpitched self-test pass tones. If the self-test is not successful, one low-pitched tone is heard. Radios with displays are able to display the error codes.
