## Abstract In this paper, an RF curveβfitting predistorter is proposed to extend the linearized dynamic range of a power amplifier. AMβAM and AMβPM distortion of the power amplifier can be compensated by accurately adjusting the gain and phase gradients of the threeβreflectionβtype diode predistor
