ABSTRACT:
In a feed-forward power amplifier, a main path amplifies a power level of an input signal to generate a path turning signal, an error path receives the input signal and controls a gain or a phase of a second order intermodulation component in the path turning signal to generate an intermodulation compensation signal, and a first synthesizer generates an output signal responsive to the path turning signal and the intermodulation compensation signal, achieving linearity.
