APC CIRCUIT The APC Automatic Power Control circuit stabilizes transmit output power to prevent transmit output power level change which is caused by load mismatching or heat effect etc The APC circuit also selects transmit output power from high middle and low power The power detector rectifies a portion of the transmit output and converts it into DC voltage which is in proportion to the transmit output power level The detected voltage is applied to the comparator The transmit power setting voltage is ap plied to another input terminal as the reference voltage The comparator compares the detected voltage and refer ence voltage and the difference of voltage is output The output voltage controls the bias of the RF amplifiers to re duce increase the gain of these amplifiers for stable transmit output power The change of transmit power is carried out by the change of reference voltage The power detector circuit PA unit D702 D703 detects the transmit power output level and converts it into DC voltage The output voltage is at a minimum level when the antenna impedance is matched with 50 and is increased when it is mismatched The detected voltage is applied to the differential amplifier MAIN unit IC2 pin 3 and the T2 signal from the D A converter MAIN unit IC12 pin 23 controlled by the CPU MAIN unit IC22 is applied to the other input for reference When antenna impedance is mismatched the detected
