Abstract
The design of radio frequency (RF) power amplifiers has become increasingly complex. With modern radio communications systems focusing on ever-higher data rates and better spectral efficiencies, these challenges to amplifier design will continue. Modulation schemes such as multilevel linear quadrature amplitude modulation (QAM) increase spectral efficiency, yet their operating envelopes fluctuate, making this approach much more sensitive to the inherent nonlinear component of power amplifier behavior??the major source of nonlinear distortion in microwave transmitters.
