Linearization is of enormous importance because of society's need for greater and greater amounts of information. Interest in reducing distortion is not new. It dates back to early years of radio. Information transmission rate is directly related to distortion level. Linearity and amplifier efficiency are also linked, with higher linearity normally yielding lower efficiency. This paper traces the evolution of power amplifier linearization from its inception to the present.
