    Circuit Description VHF (136–174 MHz) harmonics and spurious signals. Finally, it goes to the antenna for transmission. APC Circuit The APC circuit converts the drain current from the driver-stage PA and final-stage PA into a voltage, and then compares the voltage with the APC control voltage output by the MCU. The error voltage generated from the comparison adjusts the TX power by controlling the gate bias voltage of the driver-stage PA and final-stage PA.
