SECTION 4. CIRCUIT DESCRIPTION 4-1 RECEIVER CIRCUITS 2ND IF AND DEMODULATOR CIRCUITS RF CIRCUITS The signal from the 1st IF circuits is applied to the IF IC (IC2) The RX signal from the antenna is passed through the LPF which contains the 2nd IF mixer, 2nd IF AMP, FM detector, (L42 to L44, C541, C543 to C545, C646, C647 and C649), squelch circuit and AF AMP in its package.

4-3 FREQUENCY SYNTHESIZER CIRCUITS 4-4 VOLTAGE DIAGRAMS Voltage from the power supply is routed throughout the The RX VCO is composed of Q52, D48, D49 and D53. The transceiver, through regulators and switches. VCO output signal is buffer-amplified by two buffers (Q54 and Q55) and applied to the 1st IF mixer, through the LO Q33,26, SW (D55) and the LPF (L8, L12 and C69).
