SECTION 4 CIRCUIT DESCRIPTION

4-1 RECEIVER CIRCUITS

4-1-1 ANTENNA SWITCHING CIRCUIT

The antenna switching circuit functions as a low-pass filter while receiving. However, its impedance becomes very high while D9 and D10 are turned ON. Thus transmit signals are blocked from entering the receiver circuits. The antenna switching circuit employs a λ⁄4 type diode switching system.

Received signals are passed through the low-pass filter (L1, L2, C3, C5, C6). The filtered signals are applied to the λ⁄4 type antenna switching circuit (D9, D10). The passed signals are then applied to the RF amplifier circuit.

4-1-2 RF CIRCUIT

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

The signals from the antenna switching circuit are amplified at the RF amplifier (Q15) after passing through the tunable bandpass filter (D12, L21, C104, C105). The amplified signals are applied to the 1st mixer circuit (Q19) after out-ofband signals are suppressed at the 3 stages tunable bandpass filter (D13, L22, C111, C113, D14, L23, C116, C117, D15, L24, C120, C122).

Varactor diodes are employed at the bandpass filters that track the filters and are controlled by the CPU (IC7) via the D/A convertor (IC9) using T1–T4 signals. These diodes tune the centre frequency of an RF passband for wide bandwidth receiving and good image response rejection.

4-1-3 1ST MIXER AND 1ST IF CIRCUITS

The 1st mixer circuit converts the received signal into a fixed frequency of the 1st IF signal with a PLL output frequency. By changing the PLL frequency, only the desired frequency will pass through a crystal filter at the next stage of the 1st mixer.

The signals from the RF circuit are mixed at the 1st mixer (Q16) with a 1st LO signal (393.65–423.65 MHz) coming from the VCO circuit to produce a 46.35 MHz 1st IF signal.

The 1st IF signal is applied to a crystal filter (FI1) to suppress out-of-band signals. The filtered 1st IF signal is applied to the IF amplifier (Q17), then applied to the 2nd mixer circuit (IC3, pin 16).

4-1-4 2ND IF AND DEMODULATOR CIRCUITS

The 2nd mixer circuit converts the 1st IF signal into a 2nd IF signal. Adouble conversion superheterodyne system (which converts receive signals twice) improves the image rejection ratio and obtains stable receiver gain.

The 1st IF signal from the IF amplifier is applied to the 2nd mixer section of the FM IF IC (IC3, pin 16), and is mixed with the 2nd LO signal to be converted into a 450 kHz 2nd IF signal.

The FM IF IC contains the 2nd mixer, limiter amplifier, quadrature detector and active filter circuits. A 2nd LO signal (45.9 MHz) is produced at the PLL circuit by tripling it’s reference frequency.

The 2nd IF signal from the 2nd mixer (IC3, pin 3) passes through a ceramic filter (FI2) to remove unwanted heterodyned frequencies. It is then amplified at the limiter amplifier (IC3, pin 5) and applied to the quadrature detector (IC3, pins 10, 11) to demodulate the 2nd IF signal into AF signals.

4-1-5 AF CIRCUIT

AF signals from the FM IF IC (IC3, pin 9) are applied to the analog switch (IC6, pin 1) after being passed through the high-pass filter (IC5B, pins 5, 7) via the “DET” signal. The signals pass through the low-pass filter (IC5D, pins 13, 14), and then applied to the analog switch (IC6, pins 9, 10) again. The output signals from the analog swtich (IC6, pin 11) are applied to the AF power amplifier (IC4, pin 4) after being passed through the [VOL] control (SW-A/SW-B unit; R143) via the “VOLIN” and “VOLOUT” signals.

The applied AF signals are amplified at the AF power amplifier circuit (IC4, pin 4) to obtain the specified audio level. The amplified AF signals output from pin 10 as “AFOUT”signal are applied to the internal speaker (SP1) as the “SP” signal via the [SP] jack when no plug is connected to the jack.

4-1-6 SQUELCH CIRCUIT

Asquelch circuit cuts out AF signals when no RF signals are received. By detecting noise components in the AF signals, the squelch switches the AF mute switch.

A portion of the AF signals from the FM IF IC (IC3, pin 9) as “DET” signal are applied to the D/A convertor IC (IC9, pin

24). The signals from the D/A convertor (IC9, pin 23) as “SQLIN” signals are applied to the active filter section (IC3, pin 8) where noise components are amplified and detected with an internal noise detector.

The active filter section amplifies noise components. The filtered signals are rectified at the noise detector section and converted into “NOIS” (pulse type) signals at the noise comparator section. The “NOIS” signal output from IC3, pin 13, and is applied to the CPU (IC7, pin 53).

The CPU detects the receiving signal strength from the number of the pulses, and outputs “EXST”, “SO”, “SCK” signals. The signals are applied to the expander IC (IC15, pins 1, 2, 3), and then outputs “RMUT” signal from pin 4. This signal controls the analog switch (IC6, pin 13) to cut the AF signal line.

4-2 TRANSMITTER CIRCUITS

4-2-1 MICROPHONE AMPLIFIER CIRCUIT

The microphone amplifier circuit amplifies audio signals with +6 dB/octave pre-emphasis characteristics from the microphone to a level needed for the modulation circuit.

The AF signals from the microphone are applied to the microphone amplifier circuit (IC5c, pin 10) after being pass through the high-pass filter (C186, C187). The amplified AF signals are passed through the low-pass filter circuit (IC5d, pins 13, 14) via the mute switch (IC6, pin 4). The filtered AF signals are applied to the modulator circuit after being passed through the mute switch (IC6, pins 8, 9, 10).

4-2-2 MODULATION CIRCUIT

The modulation circuit modulates the VCO oscillating signal (RF signal) using the microphone audio signal.

The audio signals change the reactance of a diode (D6) to modulate an oscillated signal at the TX-VCO circuit (Q11). The oscillated signal is amplified at the buffer-amplifiers (Q5, Q7), then applied to the T/R switching circuit (D3, D4).

4-2-3 DRIVE/POWER AMPLIFIER CIRCUITS

The signal from the VCO circuit passes through the T/R switching circuit (D3) and is amplified at the YGR (Q4, Q3), pre-drive (Q2) and power amplifier (Q1) to obtain 4 W of RF power (at 7.2 V DC). The amplified signal passes through the antenna switching circuit (D1) via the power detector (D2), and low-pass filter and is then applied to the antenna connector.

The bias current of the pre-drive (Q2) and the power amplifier (Q1) is controlled by the APC circuit.

4-2-5 APC CIRCUIT

The APC circuit (IC2) protects the drive and the power amplifiers from excessive current drive, and selects HIGH or LOW output power.

The signal output from the power detector circuit (D2) is applied to the differential amplifier (IC2, pin 3), and the “T4” signal from the expander (IC9, pin 11), controlled by the CPU (IC7), is applied to the other input for reference.

When the driving current is increased, input voltage of the differential amplifier (pin 3) will be increased. In such cases, the differential amplifier output voltage (pin 4) is decreased to reduce the driving current.

4-3 PLL CIRCUIT

4-3-1 GENERAL

A PLL circuit provides stable oscillation of the transmit frequency and receive 1st LO frequency. The PLL output compares the phase of the divided VCO frequency to the reference frequency. The PLL output frequency is controlled by a crystal oscillator and the divided ratio (N-data) of a programmable divider.

The PLL circuit, using a one chip PLL IC (IC1), directly generates the transmit frequency and divided ratio based on serial data from the CPU and compares the phases of VCO signals with the reference oscillator frequency. The PLL IC detects the out-of-step phase and output from pin 5.The reference frequency (15.3 MHz) is oscillated by X1.

4-3-2 TX LOOP

The generated signal at the TX-VCO (Q11, D7) enters the PLL IC (IC1, pin 8) and is divided at the programmable divider section and is then applied to the phase detector section.

The phase detector compares the input signal with a reference frequency, and then outputs the out-of-phase signal (pulse-type signal) from pin 5.

The pulse-type signal is converted into DC voltage (lock voltage) at the loop filter (R40–R42, C75–C77), and then applied to varactor diodes (D6) of the TX-VCO to stabilize the oscillated frequency.

4-3-3 RX LOOP

The generated signal at the RX-VCO (Q10, D5) enters the PLL IC (IC1, pin 8) and is divided at the programmable divider section and is then applied to the phase detector section.

The phase detector compares the input signal with a reference frequency, and then outputs the out-of-phase signal (pulse-type signal) from pin 5.

The pulse-type signal is converted into DC voltage (lock voltage) at the loop filter (R40–R42, C74–C77), and then applied to varactor diodes (D5) of the RX-VCO to stabilize the oscillated frequency. The lock voltage is also used for the receiver circuit for the bandpass filter center frequency. The lock voltage from the loop filter is amplified at the buffer amplifier (Q13) and then applied to the CPU (IC7, pin 60). The signal is analyzed at the CPU, and then applied to the D/A convertor (IC9). The D/A convertor outputs “T1”, “T2”, “T3”, “T4” signals to RF bandpass filters D12–D15 to suppress harmonic components.

4-3-4 VCO CIRCUIT

The VCO outputs from Q11 (TX) and Q10 (RX) are buffer amplified at Q7 and Q6, and are then sent to the T/R switch (D3, D4). The receive LO signal is applied to the 1st mixer circuit (Q19) through an attenuator, and the tramsmit signal is applied to the YGR amplifier (Q4). A portion of the VCO output is reapplied to the PLL IC (IC1, pin 8) via the buffer amplifier (Q6) and low-pass filter (L18, R53, C89–C91).
