TK- 7 1 80 16 1. Outline The TK-7180 is a VHF/FM transceiver designed to operate in the frequency range of 136 to 174MHz. Transmission out- put power is 30 watts. The maximum channel capacity is 512. The unit consists of receiver, transmitter, phase-locked loop (PLL) frequency synthesizer, and control circuits.
TK- 7 1 80 17 2-5. Squelch Circuit The output signal from IC172 enters FM IC again, then passed through a band-pass filter. The noise component output from IC172 is amplified by Q175 and rectified by D173 to produce a DC Voltage corre- sponding to the noise level.
TK- 7 1 80 18 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.
TK- 7 1 80 19 6. Power Supply Circuit The block diagram of the power supply circuit is shown in Figure 6. Power is always supplied from +B to the circuit (5M, +B) that is always started and the circuits (SB, 8C, 5E, 8T, 8R, 5C, 5R) controlled by the CPU (IC404).
