4 - 1 SECTION 4CIRCUIT DESCRIPTION 4-1 RECEIVER CIRCUITS 4-1-1 ANTENNA SWITCHING CIRCUIT (RF UNIT) Received signals from the antenna connector are passed through the low-pass filter (L5, L6, C8–C12). The filtered sig- nals are applied to the λ ⁄4type antenna switching circuit (D101, D102, L4, L206, C209, C210). The passed signals are then applied to the RF amplifier circuit. The antenna switching circuit functions as a low-pass filter while receiving. However, its impedance becomes very high while D101 and D102 are turned ON (while transmitting). Thus transmit signals are blocked from entering the receiv- er circuits. The passed signals are then applied to the RF amplifier 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 amplified at the RF amplifier (Q3) and passed through the bandpass filter (FI1) to suppress out-of-band signals. The filtered sig- nals are applied to the 1st mixer circuit. 4-1-3 1ST MIXER AND 1ST IF CIRCUITS (RF UNIT) The 1st mixer circuit converts the received signals to a fixed frequency of the 1st IF signal with a PLL output frequency. By changing the PLL frequency, only desired signals will pass through a crystal filter at the next stage of the 1st mixer. The signals from the bandpass filter (FI1) are mixed at the 1st mixer circuit (Q2) with a 1st LO signal coming from the VCO circuit to produce a 21.7 MHz 1st IF signal. The 1st IF signal is applied to a crystal filter (FI2) to sup- press out-of-band signals. The filtered 1st IF signal is applied to the IF amplifier (Q1), then applied to the 2nd mixer circuit. 4-1-4 2ND MIXER AND DEMODULATOR CIRCUITS (RF UNIT) The 2nd mixer circuit converts the 1st IF signal into a 2nd IF signal. A double 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 (Q1) is applied to the 2nd mixer section in the FM IF IC (IC2, 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 a 2nd mixer, quadrature detector, noise amplifier and a limiter amplifier, etc. The PLL refer- ence oscillator (X1) is used for the 2nd LO signal via the PLL IC (IC1, pins 16, 17), and is applied to pin 1 of the FM IF IC (IC2). The mixed 2nd IF signal is output from pin 3 (IC2) and passed through the ceramic bandpass filter (FI3) to remove unwanted heterodyne frequencies. It is then amplified at the limiter amplifier section (IC2, pin 5) and applied to the quad- rature detector section (IC2, pins 10, 11) to demodulate the 2nd IF signal 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 passed through the high-pass filter (RF unit; Q15, Q16) to remove CTCSS signals then applied to the MAIN unit via J2 (pin 10) as the “VOL” signal. The “VOL” signal (AF signals) from the RF unit is applied to the [VOL] control (MAIN unit; R58) to control the audio level via the volume mute switch (Q23). The level controlled AF signals are applied to the AF power amplifier (IC9, pin 2) to drive an internal speaker (SP1) via the [SP] jack (J1). • 2nd IF and demodulator circuits Mixer 16 Limiter amp. 2nd IF filter 450 kHz PLL IC IC1 X1 21.25 MHz X2 (21.25 MHz) RSSI IC2 TA31136FN 14 1st IF (21.7 MHz) from Q1 "SQL" signal to the CPU pin 59 11109 87 53 AF signal "AF" R+3 1 17 16 Active filter FI3 Noise detector FM detector 4 - 2 4-1-6 SQUELCH CIRCUIT (RF AND MAIN UNITS) • 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. 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, pin 8). The active filter section amplifies and filters noise components. The filtered signals are applied to the noise detector section and output from pin 14 as the “SQL” signal. The “SQL” signal from IC2 (pin14) is applied to the CPU (MAIN unit; IC1, pin 59). The CPU analyzes the noise con- dition and outputs the “RMUT” and “AFON” signals to toggle the volume mute (MAIN unit; Q23) and AF mute (MAIN unit; Q5, Q10, Q11) switches. • TONE SQUELCH The tone squelch circuit detects AF signals and opens the squelch only when receiving signal containing a matching subaudible tone (CTCSS). When tone squelch is in use, and a signal with a mismatched or no subaudible tone is received, the tone squelch circuit mutes the AF signals even when 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 the CTCSS decoder inside the CPU (MAIN unit; IC1, pin 58) via the “CTCIN” line to control the volume mute and AF mute switches. 4-2 TRANSMITTER CIRCUITS 4-2-1 MICROPHONE AMPLIFIER CIRCUIT (MAIN UNIT) The microphone amplifier circuit amplifies audio signals with pre-emphasis characteristics from the microphone to a level needed for the modulation circuit. AF signals from the internal/external microphone are applied to the microphone amplifier circuit (IC2b) via the microphone mute switch (Q6) and pre-emphasis circuit (R7, C24). The amplified signals are passed through the splatter filter (IC2a) and applied to the modulation circuit in the RF unit via J4 (pin 6) as the MOD signal. 4-2-2 MODULATION CIRCUIT (RF UNIT) The modulation circuit modulates the VCO oscillating signal (RF signal) using the microphone AF signals. The filtered audio signals from the MAIN unit are passed through the deviation adjustment pot (R50), and are then applied 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 AM…
