Abstract
RF amplifier system () incorporating feedforward linearization. The system includes a digital waveform source () generating digital data s(t) representative of at least one analog signal. The system also includes a feedforward linearization circuit for reducing a distortion of an RF power amplifier (). The feedforward linearization circuit includes a differential amplifier () arranged for generating an error signal. The error signal is determined based on a difference between the distorted RF output signal and an analog RF reference signal () generated from the digital data.
