An RF power amplifier system comprises an amplitude control loop and a phase control loop. The amplitude control loop adjusts the supply voltage to the power amplifier based upon the amplitude correction signal indicating the amplitude difference between the amplitude of the input signal and an attenuated...http://www.google.es/patents/US7917106?utm_source=gb-gplus-sharePatente US7917106 - RF power amplifier controller circuit including calibrated phase control loop
