SECTION 3 CIRCUIT DESCRIPTION local oscillator section and X2 generate 31.195 MHz for the 2nd LO signal. 3-1 RECEIVER CIRCUITS 3-1-1 RF CIRCUIT (RX UNIT) Received signals from the RX antenna connector enter the RX unit J1 and pass through a tuned bandpass filter (D3, D4, L2, L3, C5–C8, C12, C13, C205, C206, C220, 221) which is controlled by the D/A converter IC (LOGIC unit; IC25). The filtered signals are applied to an RF amplifier (Q1).
nal is applied to the CPU (IC 33) via the serial signal line. 3-1-6 RECEIVER MUTE CIRCUITS (LOGIC UNIT) • NOISE SQUELCH The noise squelch circuit cuts out AF signals when no RF signals are received. By detecting noise components in the AF signals, the squelch circuit switches the AF mute switch. The DTCS signal passes through a low-pass filter circuit (IC12, pins 1, 3, 8, 10), and is then applied to the signal amplifier (IC12, pins 12, 14).
ulate the oscillated signal (TVCO unit; D5) and modulate the oscillated signal at VCO circuit (TVCO; Q1, D1–D4). The modulated VCO output is amplified at the buffer amplifier (Q1) and is then applied to the drive amplifier circuit on the PA unit. The filtered signals are applied to the limiter amplifier (IC3), and are then mixed with the DTMF signal from the CPU (IC33, pin 43) via the TX-signal filter (IC3, pins 8, 10, 12, 14).
detected voltage exceeds the power setting voltage. Then the output voltage of the APC amplifier IC (IC1, pin 4) controls the input current of the drive amplifier (Q4) and power amplifier IC (IC2, pin 2) to reduce the output power. R81, R136, R137). The filtered signal is applied to the 1st mixer circuit (RX unit; IC1) as 1st LO signal. A part of the signal is applied to the PLL IC (RX unit; IC4) via the amplifier (RX unit; Q14) as RX PLL lock voltage.
3-4 OTHER CIRCUITS 3-5 POWER SUPPLY CIRCUITS 3-4-1 TELEPHONE IF CIRCUIT (LOGIC UNIT) 3-5-1 LOGIC AND REG UNITS VOLTAGE LINES The signals from the telephone line (FRONT, J13) are applied to the ringer detect circuit (IC48, D1, D5, R131, R143, R145, C100, C103, C375). The detected signals are applied to the CPU (IC33, pin 73) via “RING” line. The “HOOKC” signal from the CPU (IC33, pin 72) and the “DP” signal from IC47 are applied to the hook switch (RL1, RL2) to off-hook.
