  • Page 16: Circuit Description

    TK-8180 1. Outline The TK-8180 is a UHF/FM transceiver designed to operate in the frequency range of 450 to 520MHz. Transmission out- put power is 30 watts (490~520MHz : 25W). The maximum channel capacity is 512. The unit consists of receiver, transmitter, phase-locked loop (PLL) frequency synthesizer, and control circuits.

  • Page 18 TK-8180 4. Frequency Synthesizer Unit 4-1. Frequency Synthesizer The frequency synthesizer consists of the TCXO (X301), VCO, PLL IC (IC301) and buffer amplifiers. The TCXO generates 16.8MHz. The frequency stability is 2.5ppm within the temperature range of –30 to +60°C. The frequency tuning and modulation of the TCXO are done to apply a voltage to pin 1 of the TCXO.
