  • Page 12: Circuit Description

    TC-600 Service Manual Circuit Description 1. Frequency Configuration The receiver utilizes double conversion superheterodyne. The first IF is 45.050MHz and the second is 455 KHz. The first local oscillator signal is supplied from PLL circuit. Frequency needed in the transmitter is supplied from PLL circuit. Figure 1 shows the frequency configuration.
  • Page 13 TC-600 Service Manual Figure 2 Receiver Section Configuration 2) The First Mixer The signal from RF amplifier is mixed with the first local oscillator signal from PLL frequency synthesizer in the first mixer (Q23) to generate a 45.050MHz first IF signal. The first IF signal is then fed through two monolithic crystal filters (XF1) to remove spurious signals from adjacent channels.
