Abstract
A radio frequency (RF) power amplifier system is provided, in which a distortion of the RF output signal from the power amplifier is estimated by comparing the RF output signal with reference modulation information. The supply voltage to the power amplifier is adjusted so that the estimated distortion of the RF output signal corresponds to a predetermined distortion level. The predetermined distortion level is set to represent an acceptable distortion level at the RF output signal.
