Adaptive Ways for Feed-forward Power Amplifier
FU Rui-gai · Radio Engineering of China · 2007
It is necessary to use linearization technique in the power amplifier.This paper introduces the principle of feed-forward power amplifier.The working states are influenced by the change of external environment,so the adaptive feed-forward power amplifier is proposed.There are three adaptive ways:pilot signal,minimizing the measured power signal and relativity of the measured power signal.The three adaptive ways are analyzed.By comparison,minimizing the measured power signal is the best.
