Abstract
A system and method for employing a training scheme to a linear amplifier system having a modulator component for modulation of a supply power of an RF power amplifier. A supply modulator is set at a maximum or peak supply voltage of the RF power amplifier that corresponds to a maximum saturation point of the RF power amplifier. A training mode is entered wherein an input signal is provided and a phase adjustment and an attenuation level for the input signal to the RF power amplifier is determined. The phase adjustment and attenuation level is employed in normal operation. A relationship between the maximum clip level and maximum supply voltage and the instantaneous voltage level of the supply that will be utilized to modulate the reference signal is employed to determine the attenuation level.
