Abstract

Certain applications demand band specific linearity i.e removing harmonics which lie in a specific band while the rest of the spectrum is kept unaffected. The shape of the signal waveform changes by altering the amplitude and phase of these harmonics. This change in shape of the signal affects power efficiency (PE) in different ways. The effects become more dominant for power amplifiers driving a large load. In this paper, some effects of harmonic cancellation on PE are observed and documented. The waveform used is a square wave in low frequency domain.
