Page 13: Circuit Description
CIRCUIT DESCRIPTION 1. Overview 3. Receiver System The KENWOOD model TK-6110 is a VHF/FM transceiver 3-1. Front-End RF Amplifier designed to operate in the frequency range of 29.7 to An incoming signal from the antenna is applied to a band- 37MHz (K), 35.0 to 50.0MHz (K2), the unit consists of a re-...
Page 14 TK-6110 CIRCUIT DESCRIPTION 3-4. Audio Amplifier Circuit The recovered audio signal obtained from IC202 is ampli- fied by IC709, IC713, low-pass filtered by IC713 high-pass filtered by IC713 and band-eliminate filtered by IC713. The audio signals then passed through a de-emphasized by IC713.
Page 15 TK-6110 CIRCUIT DESCRIPTION 4-4. Driver and Final Power amplifier Circuits 5. PLL Frequency Synthesizer The transmit signal is generated by the TX mixer (Q503). The frequency synthesizer consists of the VCXO (X501), The transmit signal obtained from the buffer amplifier Q1 VCO (L517), PLL IC (IC501) and buffer amplifiers.
Page 16 TK-6110 CIRCUIT DESCRIPTION IC605 6. Power Supply Circuit EEPROM The power (+B), which is suplied via a power connector, is routed to the TX drive amplifier (Q4 and Q5), the TX final IC606 amplifier (Q6 and Q7), and the audio power amplifier...
