38. TCHING CIRCUIT MAIN UNIT The antenna switching circuit functions as a low pass filter while receiving and as resonator circuit while transmitting The circuit does not allow transmit signals to enter receiver circuits Received signals from the antenna connector pass through the low pass filter 181 L82 C83 C86 C89 and antenna switching circuit D52 D90 The filtered signals are then applied to the RF amplifier circuit Q90 4 1 2 RF AND 1ST MIXER CIRCUITS MAIN UNIT The 1st mixer circuit converts the received signals to a fixed frequency of the 1st IF signal with a PLL output frequency By changing the PLL frequency only the desired frequency will be passed through a pair of crystal filters at the next stage of the 1st mixer The signals from the antenna switching circuit are passed through the tunable bandpass filter D92 and amplified at the RF amplifier Q90 The amplified signals are passed through another tunable bandpass filter D130 and then applied to the 1st mixer circuit Q150 The filtered signals are mixed at the 1st mixer Q150 with a 1st LO signal coming from the PLL circuit to produce a 21 7 MHz 1st IF signal The 1st IF signal is passed through two crystal filters F1150 Fl151 and is then amplified at the IF amplifier Q151 2ND IF AND DEMODULATOR CIRCUITS H175 signal to the D A convertor IC 1C190 pin 15 4 1 3 2ND IF AND DEMODULATOR CIRCUITS MAIN UNIT The 2nd mixer c
