Abstract :
Signal linearity is becoming an increasingly important requirement for the high power amplifiers used in current wireless communications systems. In this paper we demonstrate an input matching topology to improve the overall linearity performance of the base-station power amplifier. We then show simulation and measurement results using high-power laterally diffused metal oxide semiconductor (LDMOS) RF transistor and digital predistortion system for prototype design.
