Patent abstract
An enhanced Doherty-configured amplifier that features separate and independent bias voltage sources for the main and auxiliary amplifiers. The bias voltage sources may be controllable and variable to alter the performance of the amplifier according to the input signal or system requirements. The enhanced amplifier includes a signal preparation unit to divide and shape the input signal in order to compensate for non-linearities in the combined output signal.
