SECTION 4 CIRCUIT DESCRIPTION 4-1 RECEIVER CIRCUITS 4-1-2 1ST MIXER AND IF CIRCUITS (MAIN UNIT) 4-1-1 RF FILTER CIRCUIT (PLL AND MAIN UNITS) The 1st mixer circuit converts the received signals into a fixed frequency, 64.445 kHz 1st IF signal using PLL output frequency. By changing the PLL frequency, only the desired frequency is picked up at the 64.445 kHz bandpass filter (FI201) at the next stage.
The receiver gain is determined by the voltage on the AGC1 line from the DSP unit. The D/A converter for the AGC (IC9102) supplies control voltage to the AGC1 line and sets the receiver gain with the [RF/SQL] control. 4-1-5 DSP RECEIVER CIRCUIT (MAIN AND DSP UNITS) The DSP (Digital Signal Processor) circuit enables digital IF filter, digital noise reduction, digital PSN (Pulse Shift Network), phase demodulation, digital automatic notch, and etc.
When the speech compressor function is ON, the level-shifted signal from the CODEC IC (IC9501) is applied to the DSP IC (IC9301) and compressed at the DSP IC to obtain an average audio level. 4-2 TRANSMITTER CIRCUITS 4-2-1 MICROPHONE AMPLIFIER CIRCUIT (RC-26, MAIN AND DSP UNITS) The microphone amplifier circuit amplifies microphone audio signal to a level needed for the DSP circuit.
• 2.5–3.49999 MHz signals The signals are applied to the relay (FILTER unit; RL7061). The signals pass through the low-pass filter (FILTER unit; L7067, L7068, C7072, C7073, C7077–C7083), and are then applied to the RL7062 which is controlled by the band control IC (MAIN unit; IC3602) as the “L2M” signal via the buffer amplifier (MAIN unit; IC1301, pin 14). 4-2-5 RF CIRCUIT (MAIN, PA, PLL UNITS AND DRIVER BOARD) The RF circuit amplifies operating (transmitting) frequency to obtain 100 W (125 W: 1.
4-2-6 ALC CIRCUIT (PLL AND MAIN UNITS) 4-2-8 RF METER CIRCUIT (MAIN UNIT) The ALC (Automatic Level Control) circuit controls the gain of IF amplifiers in order for the transceiver to output a constant RF power even when the supplied voltage shifts, etc. The output of ALC amplifier (IC1201, pin 14) is applied to the CPU (IC3303, pin 97) as “RFML” signal to indicate the transmit power level on the display.
4-4 FRONT UNIT (RC-26) The detected signal output from the PLL IC (pin 2) is converted into a DC voltage (lock voltage) at the loop filter and then fed back to one of the VCO circuits (Q5521, D5521, L5523). 4-4-1 LCD CIRCUIT (DISPLAY AND CONNECT BOARDS) The LCD (CONNECT board; DS8920) is controlled by the LCD driver (CONNECT board; IC8940) via the drive signals (CL1, RES, CS, RS, WR, RD, DB0–DB7) from the display board. The LCD’s back light employs 5 LEDs (DS8300–DS8304).
4-5-4 MAIN UNIT VOLTAGE LINE 4-5 POWER SUPPLY CIRCUITS 4-5-1 PA UNIT VOLTAGE LINE LINE HV13 LINE DESCRIPTION The voltage from an external power supply. HV The same voltage as the HV13 line passed through the fuse (F6701). S13V The same voltage as the HV13 line passes through the switching relay (RL6701).
