    TC-610P Service Manual Circuit Description 1. PLL Frequency Synthesizer The PLL circuit mainly provides the local oscillator signal for Rx and RF carrier signal for Tx. It is composed of VCO and baseband processor, allowing frequency tracking and channel switching under the control of MCU signals.
  • Page 14 TC-610P Service Manual In Tx mode, the oscillator frequency of VCO is generated by Q100; in Rx mode, it is generated by Q101. U202 generates, via the phase comparator, a control voltage to control varactors (D100 and D101 in Tx mode;...

  • Page 16 TC-610P Service Manual The mixer circuit mainly mixes the local oscillator signal from VCO with the received RF signal, to provide the first IF singal for frequency discrimination by the demodulator chip (active mixer is applied). The mixer Q501 uses a dual-gate MOSFET (3SK318), and is characterized by good noise characteristic, square-law characteristic, and high isolation degree between the first local oscillator signal and the Rx signal.
  • Page 17 TC-610P Service Manual The error detect voltage is derived after the Tx current goes through R420, R421 and R422. Then the voltage is compared and amplified by the operational amplfier U430, and further compared with the APC reference voltage. After these operations, the APC control voltage is output, and the close-loop negative feedback control power is generated when the Tx current changes.

The power supply of the Tx and Rx circuits are protected by symmetrical voltage regulation measures. When output voltage/current changes along with the change of load, the close-loop feedback circuit operates, regulating the output voltage to 5V.
