SECTION 4. CIRCUIT DESCRIPTION 4-1 RECEIVE CIRCUITS 2ND IF CIRCUIT AND DEMODULATOR RF CIRCUIT The signal from the 1st IF circuits is applied to the IF The RX signal from the antenna is passed through the LPF demodulator IC (IC16) which contains the 2nd IF mixer, 2nd (L29 to L31, C333, C347 to C350, C352 and C403) and IF AMP, FM detector, and so on.
4-2 TRANSMIT CIRCUITS 4-3 FREQUENCY SYNTHESIZER CIRCUITS TX AF CIRCUIT The RX VCO is composed of Q25, D9, D10 and D32. The output signal is amplified by two buffers (Q31 and Q31) and The audio signal from the internal or external microphone applied to the 1st IF mixer (Q37), through the LO SW (D17) (MIC signal) is passed through the MIC gain SW (IC2) and and LO filter (LPF*: L41, C296 and C441, or HPF**: L21,...
