High efficiency and linear power amplification for OFDM signal by combining dynamic bias and digital baseband predistortion

This paper presents a technique that enables both efficiency and linearity enhancements for power amplifiers (PA) used in communication systems. It is here applied to a 100 W wide-band LDMOS push-pull amplifier (50-500 MHz) driven by OFDM signals. When the amplifier is driven by a CW signal and oper...
