  • Page 16: Circuit Description

    TM-600 SERVICE MANUAL Circuit Description 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 PLL circuit. The second (50.4MHz) is generated from the frequency tripling of TCXO (16.8MHz). The PLL circuit generates the frequencies required for transmission.

  • Page 17: Transmitter Circuit

    TM-600 SERVICE MANUAL to become a 49.95MHz first IF signal. The first IF signal is then fed through crystal filter (IF200) to further remove spurious signals. 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.
