Abstract
An apparatus and method for amplifying a radio frequency signal including, generating a plurality of shaped pulses utilizing a piecewise linearizer circuit, applying the plurality of shaped pulses to a first input of a radio frequency amplifier circuit, and injecting a radio frequency carrier into a second input of the radio frequency amplifier circuit. The apparatus comprises a piecewise linearizer (PWL) circuit coupled to the input of a Radio Frequency Digital to Analog Converter (RFDAC) operating as a signal amplifier.
