8 SCTION CIRCUIT DSCRIPTION - RCIVR CIRCUITS -- DUPLXR CIRCUIT (RF UNIT) The transceiver has a duplexer (low-pass and high-pass filters) on the frist stage from the antenna connector to separate the signals into below UHF and SHF signals. The highpass filter (L L, C C and C C0) is for SHF (00 MHz) signal and the low-pass filter (C, C0, C C and L L) is for below UHF (0 MHz, MHz, 0 MHz and WFM) signals. The filtered SHF signal is applied to the low-pass fileter (C C, L and L). The RF signals below UHF pass through the duplexer circuit and are separated into VHF (0 MHz, MHz and WFM band) and UHF (0 MHz band) signals. The high-pass filter (C C, L, L) is for UHF (0 MHz band) signal and the low-pass filter (C C0, L0 L) is for VHF (0 MHz, MHz and WFM band) signals. The VHF signals are applied to the another duplexer circuit for separation into 0 MHz and above WFM band signals. The high-pass filter (C C, C and L L) is for MHz and WFM band signals and the low-pass filter (C C and L L) is for 0 MHz band signal. The separated signals are applied to each RF circuits. -- ANTNNA ITCHING CIRCUITS (RF UNIT) The antenna switching circuit functions as a low-pass filter while receiving. However, its impeadance becomes very high while transmitting by applying a current to D0 and D0 (0 MHz), D0 and D0 (MHz and WFM), D0 and D0 (0 MHz), D and D (00 MHz). Thus, transmit signals are blocked from entering the receiver circuits. The antenna switching circuit employs a /λ type diode switching system. The passed signals are then applied to each RF amplifier circuit MHz BAND RF CIRCUIT (RF UNIT) The RF circuit amplifies signals within the range of frequency coverage and filters out-of-band signals.

MHz st IF signal. The st IF signal is output from the st mixer (IC0, pin ), and then passed through the crystal bandpass filter (FI0) to suppress unwanted harmonic components. The filtered st IF signal is applied to the IF amplifier (IC0). The amplified signal is applied to the nd mixer circuit (LOGIC unit; IC0, pin ). WFM band The RF signals are mixed with st LO signals at the st mixer (IC0) to produce a. MHz st IF signal. The st IF signal is output from the st mixer (IC0, pin ), and then passed through the st IF filter (FI0) to suppress unwanted harmonic components.

10 -- ND IF AND DMODULATOR CIRCUITS (RF AND LOGIC UNITS) The nd mixer circuit converts the st IF signal to the nd IF signal.

The filtered st IF signal from the st IF filter (RF unit; FI0 or FI0) is mixed with the nd LO signal at the nd mixer (LOGIC unit; IC0) to produce the 0 khz nd IF signal. The nd IF signal passes through or bypasses (WFM mode signal) nd IF filter (FI0) where unwanted heterodyne signals are suppressed via the mode switch (LOGIC unit; D0, D0). The filtered signals are applied to the limiter amplifier section (LOGIC unit; IC0, pin ), and then applied to the quadrature detector section to demodulate the nd IF signal into AF signals. The demodulated AF signals are output from pin of the IF IC (LOGIC unit; IC0) and are applied to the AF circuit. -- AF LIFIR CIRCUIT (LOGIC UNIT) The AF amplifier circuit which is included a low-pass and high-pass filter, AF mute switch, AF volume controller and AF amplifier amplifies the demodulated AF signals to drive a speaker. The demodulated AF signals (DTO signal) from the FM IF IC (IC0) are passed through the AF filter (low-pass and high-pass filters). The filtered signals are applied to the AF mute switch (Q) which is controlled by RM/MM signals from the CPU (IC, pin ), and are then applied to the electric volume control circuit (IC0, IC0).

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 (IC0, pin ) are applied to the active filter section (IC0, pin, ). The active filter section amplifies and filters noise components. The filtered signals are applied to the noise detector section and output from IC0 (pin ) as NOIS signal. ven when the squelch is closed, the AF mute switch (Q) opens at the moment of emitting beep tones. TON SQULCH The tone squelch circuit detects AF signals and opens the squelch only when receiving a 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 (IC0, pin) passes through the AF filter (IC) to remove AF (voice) signals and is applied to the CTCSS decoder inside the CPU (IC, pin ) via the CTCIN line to control the AF mute switch. - TRANSMITTR CIRCUITS -- MICROPHON LIFIR CIRCUIIT (LOGIC UNIT) The microphone amplifier circuit amplifies the audio signals from the microphone, within db/octave pre-emphasis characteristics (00 Hz khz), to a level needed for the modulation circuit.

The modulated signals are amplified at the buffer-amplifier (Q) and the LO amplifier (Q). The amplified signals are applied to the drive/power amplifier circuits for VHF band. () MHz band The signals from the limiter amplifier (RF unit; IC0) changes the reactance of a diode (VCO unit; D0) to modulate the oscillated signal at the -VCO circuit (VCO unit; Q, Q, D0, D D).
