Page 7: Circuit Description
TK-2180 CIRCUIT DESCRIPTION 1. Overview 3. Receiver System This transceiver is VHF/FM portable transceiver designed 3-1. RF unit to operate in the frequency range of 136 to 174MHz. An incoming RF signal from the antenna terminal is passed through the antenna switch (D106, D107, D211 and D213 are off) and then the bandpass filter (L215, L216).
Page 8 TK-2180 CIRCUIT DESCRIPTION 3-3. Wide/Narrow switching circuit When SP-MIC is attached, SSW is connected to GND at inside of SP-MIC. For this reason, Q618 is turned off, and the Wide and Narrow settings can be made for each channel AF signal is input only to amplifier for EXT SP of IC609.
Page 9 TK-2180 CIRCUIT DESCRIPTION The output signal from the summing amplifier goes to the 4. Transmitter System VCO modulation input. The other output signal from the 4-1. Microphone amplifier summing amplifier passes through the D/A converter (IC605) The signal from the internal microphone goes through the again for the BAL adjustment, and the buffer amplifier mute switch (Q614).
Page 10 TK-2180 CIRCUIT DESCRIPTION 5. Frequency Synthesizer Unit 6. Control Circuit 5-1. Frequency synthesizer The control circuit consists of microprocessor (IC502) and its peripheral circuits. It controls the TX-RX unit and transfers The frequency synthesizer consists of the TCXO (X1), data to the Display unit. IC502 mainly performs the follow- VCO, PLL IC (IC1) and buffer amplifiers.
