Abstract
The present invention is a method and apparatus for linearizing a non-linear portion of a first response of a power amplifier in response to an input signal over an operating range. A linearizing module preprocesses the input signal. The linearizing module provides a second response which is complementary to the first response in the non-linear portion of the first response. The power amplifier processes the preprocessed input signal to generate a result response which is linear over the operating range.
