  • Page 23: Circuit Description

    TM-610 Service Manual Circuit Description 1. Frequency Configuration The receiver utilizes double conversion superheterodyne. The first IF is 49.95MHz and the second is 450KHz. The first local oscillator signal is supplied by the PLL circuit; and the second (50.4MHz) is generated from the frequency tripling of TCXO (16.8MHz).

  • Page 24: Transmitter Circuit

    TM-610 Service Manual 2.3 IF Amplifier The first IF signal is amplified by Q113 and then enters IC102 (TA31136FN), where the signal is mixed again with the second local oscillator signal (50.4MHz) to become a 450KHz second IF signal. The second IF signal is then fed through a ceramic filter (N: CF202;...
