Abstract

This paper has been studied a predistorter which is able to linierizing of RF amplifier using schottkey. If input signal level is low, input signal is delivered directly. And if input signal level is high, input signal Is delivered with decreasing. So RF amplifier always works at saturation region .When this predistorter is used to simplified C-class RF amplifier, we have concluded that efficiency is improved about 3%.
