  • Page 11 QP-650U Plus Circuit Description Circuit Description 1. Power Supply Power supply of the radio is derived from the battery, which supplies battery B+ through power switch. U608 supplies 5V (5M) voltage for the control circuit. U607 supplies 3V voltage for the PLL circuit. And U200 supplies voltage for the transmit(V_TX), receive(V_RX) and vco(V_SAVE) circuit.
  • Page 12 QP-650U Plus Circuit Description The output signal from phase comparator is filtered through a low pass filter to generate a level D.C., and the level D.C. controls oscillator frequency by controlling VCO. The operating frequency is generated by Q100 in transmit mode and by Q101 in receive mode. Operating frequency generate a control voltage by phase comparator to control varactor diodes so that the oscillator frequency is consistent with the MCU preset frequency(D100、D101、D104 and D105 in transmit mode, and D102、D103、D106 and D107 in receive mode).
