Abstract

This paper proposes a polar function linearizer to reduce the spectral regrowth of radio frequency power amplifier using even order harmonic signals. An AM modulator, modulate fundamental signal with even order harmonic signals, makes inverse transfer function of power amplifier and controls amplitude and phase of them with polar function factors. As a result, this polar function linearizer is suppressed intermodulation distortion signals of power amplifier effectively.
