PA Circuit TX RF signal output from Q703 in the VCO circuit is amplified at Q101 driver PA Q110 and Q109 and final stage PA IC101 The signal passes through LPF and goes to the antenna for transmission 3 3 APC Circuit The circuit is used to keep output power at a constant preset value In this circuit D101 and D102 convert the signal from detector into DC voltage which is then compared with the reference voltage from CPU in 104 to output a DC voltage The DC voltage controls gate electrode of IC101 so as to control the output power 4 PLL Circuit PLL circuit supplies frequency to receive the first LO signal and TX signal The circuit consists of TX frequency oscillator Q701 RX frequency oscillator Q702 buffer amplifier Q703 RF amplifier 0102 PLL IC 801 LPF and TX RX VCO switch 0704 0706 In TX mode 502 provides the frequency data to and activates PLL IC Meanwhile Q704 is turned on to activate TX VCO The output signal is amplified by Q703 and Q102 Then PLL IC divides the signal into 2 5KHz 5KHz or 6 25KHz And phase of it is compared with that of reference frequencies 2 5KHz 5KHz or 6 25KHz from the 16 8MHz crystal oscillator The crystal oscillator has operating frequency of 16 8MHz and frequency stability of 2 5ppm The frequency control voltage output from the phase comparator passes through LPF Q802 and Q803 and then is sent to TX VCO In the meantime TX modulation signal is passed to TX VCO for fr

68. 12 MCF IF200 N 0 ASQ LPF A RX VCO i gt gt 14 16502 CF203 Fig 1 Receiver Circuit 2 1 RF AMP BPF The circuit consists of front stage BPF RF amplifier Q111 and final stage BPF D110 and D111 The bandpass frequency range varies with the radio models The BPF is used to eliminate unwanted signals and let only wanted signals go to the mixer 2 2 First Mixer Circuit The signal output from RF AMP amp BPF is mixed with the first LO signal from the PLL circuit at the mixer Q112 to generate a 49 95MHz first IF signal Then the first IF signal will feed through a crystal filter XF200 to further remove spurious signals 2 3 IF Amplifier Circuit After amplified at Q113 the first IF signal enters IC102 BA4116FV where it is mixed with the second LO signal 49 5MHz to generate a 450KHz second IF signal Then the second IF signal feeds through a 13 TM 628H Service Manual pair of ceramic filters N CF202 W CF203 where unwanted signals are removed Finally the signal goes to the frequency discriminating circuit of 1 102 to output audio signal from Pin 9 2 4 Audio Amplifier Circuit The audio signal from 1 102 is amplified and filtered at IC402 and then amplified again at 401 the received signaling is separated and sent to CPU for decoding Then the signal passes through Q406 AF MUTE and enters 405 for further amplification After the volume is control
