SECTION 4 CIRCUIT DESCRIPTION

4-1 RECEIVER CIRCUITS4-1-1 ANTENNA SWITCHING CIRCUIT

(MAIN UNIT)Received signals passed through the low-pass filter (L44,L47, L48, L51, C190, C197, C203, C208, C210, C217,C218). The filtered signals are applied to the 1/4 λ typeantenna switching circuit (D16, D19).

The antenna swtiching circuit functions as a low-pass filterwhile transmitting. However, its impedance becomes veryhigh while D16 and D19 are turn ON. Thus transmit signalsare blocked from entering the receiver circuits. The antennaswitching circuit employs a 1/4 λ type diode swtiching sys-tem. The passed signals are then applied to the RF amplifi-er circuit.

4-1-2 RF CIRCUIT (MAIN UNIT)

The RF circuit amplifies signals within the range of frequen-cy coverage and filters out-of-band signals.

The signals from the antenna switching circuit are applied tothe limitter (D15), and are then passed through the band-pass filter (D13, L43, C183, C182). The filtered signals areamplified at the RF amplifier (Q27), then applied to the 1stmixer circuit after out-of-band signals are suppressed at thebandpass filter (D9–D11).

D9–D11, D13 employ varactor diodes that track the band-pass filters and are controlled by the T1–T3 signals from theD/A convertor (IC5, pins 10, 11, 23). These diodes tune thecenter frequency of an RF passband for wide bandwidthreceiving and good image response rejection.

4-1-3 1ST MIXER AND 1ST IF CIRCUITS(MAIN UNIT)

The 1st mixer circuit converts the received signal to a fixedfrequency of the 1st IF signal with a PLL output frequency.By changing the PLL frequency, only the desired frequencywill pass through two crystal filters at the next stage of the1st mixer.

The signals from the RF circu(Q19) with a 1st LO signal coproduce a 21.70 MHz 1st IF siThe 1st IF signal is applied to twto suppress out-of-band signalsapplied to the IF amplifier (Qmixer circuit (IC4, pin 16).

The AF signals are applied to the AF power amplifier circuit(IC9, pin 1) to obtain the specified audio level. The amplifiedAF signals, output from pin 4, are applied to the internalspeaker (CHASSIS UNIT; SP1) via the speaker jack (J6)

when no plug is connected to the external speaker jack (J1).

4-1-6 SQUELCH CIRCUIT(MAIN AND LOGIC UNITS)

A squelch circuit cuts out AF signals when no RF signals arereceived. By detecting noise components in the AF signals,the squelch switches the analog swtich.

A portion of the AF signals from the FM IF IC (IC4, pin 9) areapplied to the D/A converter (IC5, pin 13) as the DETO sig-nal. The signals from the D/A converter (IC5, pin 14) areapplied to the FM IF IC active filter section (IC4, pin 8) wherenoise components are amplified and detected with an inter-nal noise detector via the SQLIN line.

The trigger circuit converts the detected signals to a HIGHor LOW signal and applies this (from pin 13) to the CPU(LOGIC UNIT; IC7, pin 19) as the NOIS signal.The CPU

controls the analog swtich IC (LOGIC UNIT; IC6) via theexpander IC (LOGIC UNIT; IC8). When the CPU receives aHIGH level NOIS signal, the CPU controls the RMUT line tocut the AF signals at the analog swtich IC (LOGIC UNIT;IC6). At the same time, the AFON line controls the AF mutecircuit (Q29) to cut out the VOLOUT signal for the AF poweramplifier (IC9).

4-2 TRANSMITTER CIRCUITS4-2-1 MICROPHONE AMPLIFIER CIRCUIT

(LOGIC AND MAIN UNITS)The microphone amplifier circuit amplifies audio signals with+6 dB/octave pre-emphasis from the microphone to a levelneeded for the modulation circuit.

The AF signals from the microphone pass through the MICswitch (IC2, D4) and high-pass filter (IC3a, pin 2), and arethen applied to the microphone amplifier circuit (IC3d, pin12) via the R39 and C47 for +6 dB/octave pre-emphasis.The amplified AF signals are applied to the analog swtich(IC6, pin 4), and are then applied to the D/A converter (MAINUNIT; IC5, pin 1) via the MODIN signal. The AF signals areapplied to the modulator circuit via the MOD signal.

4-3 PLL CIRCUITS4-3-1 PLL CIRCUIT (MAIN AND LOGIC UNITS)A PLL circuit provides stable oscillation of the transmit fre-quency and receive 1st LO frequency. The PLL output com-pares the phase of the divided VCO frequency to the refer-ence frequency. The PLL output frequency is controlled bythe divided ratio (N-data) of a programmable divider.

An oscillated signal from the TX and RX-VCO circuits pass-es through the LO and buffer amplifiers (Q9, Q12) is appliedto the PLL IC (IC1, pin 6) and is prescaled in the PLL ICbased on the divided ratio (N-data). The reference signal isgenerated at the reference oscillator (X1) and is also applied

to the PLL IC. The PLL IC detects the out-of-step phaseusing the reference frequency and outputs it from pin 15.The output signal is passed through the loop filter(Q2) andis then applied to the TX and RX-VCO circuits as lock volt-age.

The lock voltage is also used for the receiver tunable band-pass filters to match the filter’s center frequency to thedesired receive frequency. The lock voltage is passedthrough the loop filter (Q2), and then applied to the DCamplifier (Q10). The amplified signal is applied to the CPU(LOGIC unit; IC7, pin 98) via the “LVIN” signal. The signal isanalyzed at the CPU, and then applied to bandpass filters(D9–D11, D13) as “T1”, “T2”, “T3” signals via the D/A con-verter.

4-3-2 VCO CIRCUIT (MAIN UNIT)The VCO circuit contains a separate TX-VCO (Q6, D2, D4)and RX-VCO (Q7, D5). The oscillated signal is amplified atthe LO (Q9) and buffer (Q11) amplifiers, and is then Tx/Rxswitching circuit (D6, D7). Then Tx and Rx signals areapplied to the pre-driver (Q17) and 1st mixer circuit (Q19)respectively.

A portion of the signal from LO amplifier (Q9) is amplified atthe buffer amplifier (Q12) and is then fed back to the PLL IC(IC1, pin 6) as the comparison signal.
