SECTION 4 CIRCUIT DESCRIPTION

4-1 RECEIVER CIRCUITS4-1-1 ANTENNA SWITCHING CIRCUIT (RF UNIT)Received signals from the antenna connector are passedthrough the low-pass filter (L5, L6, C8–C12). The filtered sig-nals are applied to the λ⁄4 type antenna switching circuit (D7,D101, D102, L4, L206, C209, C210).

The antenna switching circuit functions as a low-pass filterwhile receiving. However, its impedance becomes very highwhile D101 and D102 are turned ON (while transmitting).Thus transmit signals are blocked from entering the receivercircuits. The passed signals are then applied to the RF ampli-fier circuit.

4-1-2 RF CIRCUIT (RF 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 amplifiedat the RF amplifier (Q3) and passed through the bandpass fil-ter (FI1) to suppress out-of-band signals. The filtered signalsare applied to the 1st mixer circuit (Q2).

4-1-3 1st MIXER AND 1st IF CIRCUITS (RF UNIT)The 1st mixer circuit converts the received signals to a fixedfrequency of the 1st IF signal with a PLL output frequency. Bychanging the PLL frequency, only desired signals will bepassed through a crystal filter at the next stage of the 1stmixer.

The signals from the bandpass filter are mixed at the 1stmixer circuit (Q2) with a 1st LO signal coming from the VCOcircuit to produce a 21.7 MHz 1st IF signal.The 1st IF signalis applied to a crystal filter (FI2) to suppress out-of-band sig-nals. The filtered 1st IF signal is applied to the IF amplifier(Q1), then applied to the 2nd mixer circuit (IC2, pin 16).

4-1-4 2nd MIXER AND DEMODULATOR CIRCUITS(RF UNIT)

The 2nd mixer circuit converts the 1st IF signal to a 2nd IFsignal. A double conversion superheterodyne system (whichconverts receive signals twice) improves the image rejectionratio and obtains stable receiver gain.

The 1st IF signal from the IF amplifier (Q1) is applied to the2nd mixer section in the FM IF IC (IC2, pin 16), and is mixedwith the 2nd LO signal to be converted into a 450 kHz 2nd IFsignal.

The FM IF IC contains a 2nd mixer, quadrature detector,noise amplifier and a limiter amplifier, etc. The PLL referenceoscillator (X1) is used for the 2nd LO signal via the PLL IC(IC1, pins 11, 9), and is applied to pin 1 of the FM IF IC (IC2).

The mixed 2nd IF signal is output from pin 3 and passedthrough the ceramic bandpass filter (FI3) to remove unwant-ed heterodyne frequencies. It is then amplified at the limiteramplifier section (IC2, pin 5) and applied to the quadraturedetector section (IC2, pins 10, 11) to demodulate the 2nd IFsignal into AF signals.

4-1-5 AF CIRCUIT (RF AND MAIN UNITS)AF signals from the FM IF IC (RF unit; IC2, pin 9) are passedthrough the high-pass filter (RF unit; Q15, Q16) to removeCTCSS signals then applied to the MAIN unit via J2 pin 10 asthe “VOL” signal.

The “VOL” signal (AF signals) from the RF unit is applied tothe [VOL] control (MAIN unit; R58) to control the audio levelvia the volume mute switch (Q23). The level controlled AFsignals are applied to the AF power amplifier (IC9, pin 2) todrive an internal speaker (SP1) via the [SP] jack (J1).

4-1-6 SQUELCH CIRCUIT (RF AND MAIN UNITS)(1) NOISE SQUELCHThe noise squelch circuit cuts out AF signals when no RF sig-nals are received. By detecting noise components in the AFsignals, the squelch circuit switches the AF mute switch.

A portion of the AF signals from the FM IF IC (RF unit; IC2,pin 9) are applied to the active filter section (RF unit; IC2, pin8). The active filter section amplifies and filters noise compo-nents. The filtered signals are applied to the noise detectorsection and output from pin 14 as the “SQL” signal.

The “SQL” signal from IC2 (pin 14) passes through J2 pin 9,and is then applied to the CPU (MAIN unit; IC1, pin 59). TheCPU analyzes the noise condition and outputs the “RMUT”and “AFON” signals to toggle the volume mute (MAIN unit;Q23) and AF mute (MAIN unit; Q5, Q10, Q11) switches.

(2) TONE SQUELCHThe tone squelch circuit detects AF signals and opens thesquelch only when receiving a signal containing a matchingsubaudible tone (CTCSS). When tone squelch is in use, anda signal with a mismatched or no subaudible tone isreceived, the tone squelch circuit mutes the AF signals evenwhen noise squelch is open.

A portion of the AF signals from the FM IF IC (RF unit; IC2,pin 9) passes through the tone low-pass filter (MAIN unit; Q7,Q12) to remove AF (voice) signals and is applied to theCTCSS decoder inside the CPU (MAIN unit; IC1, pin 58) viathe “CTCIN” line to control the volume mute and AF muteswitches.

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

(MAIN UNIT)AF signals from the internal/external microphone are appliedto the microphone amplifier circuit (IC2b) via the microphoneswitch (Q6). The amplified signals are passed through thelow-pass filter (IC2a) and applied to the modulation circuit inthe RF unit via J4 pin 5 as the MOD signal.

4-2-2 MODULATION CIRCUIT (RF UNIT)The filtered audio signals from J4, pin 5 (On the MAIN unit)are passed through the deviation adjustment pot (R50) thenapplied to the modulation circuit (D4, D5) to modulate trans-mit signals at the VCO circuit (Q6).

The modulated signal is applied to the drive amplifier circuit.

4-2-3 DRIVE/POWER AMPLIFIER CIRCUITS(RF UNIT)

The amplifier circuit amplifies the VCO oscillating signal tothe output power level.

The amplified transmit signal is passed through the antennaswitching circuit (D6) and low-pass filter, and is then appliedto the antenna.

The modulated transmit signal is amplified at the pre-driveand drive amplifiers (Q8, Q201) after being amplified at thebuffer amplifier (Q7). The amplified signal is power amplifiedat the power amplifier (Q202) to obtain 500 mW or(IC–4008A) 10 mW (IC–4008MK2) of RF power.

The power amplified signal is then applied to the antenna viathe low-pass filter circuits.

4-3 PLL CIRCUITS (RF UNIT)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.

The PLL circuit consists of the VCO circuit (Q6, D4, D5). Anoscillated signal from the VCO passes through the bufferamplifier (Q7) is applied to the PLL IC (IC1, pin16) and isprescaled in the PLL IC based on the divided ratio (N-data).The reference signal is generated at the reference oscillator(X1) and is also applied to the PLL IC. The PLL IC detects theout-of-step phase using the reference frequency and outputsit from pin 14. The output signal is passed through the loopfilter (R45, C68) and is then applied to the VCO circuit as thelock voltage.

If the oscillated signal drifts, its phase changes from that ofthe reference frequency, causing a lock voltage change tocompensate for the drift in the oscillated frequency.
