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)...
Integrating a CMOS RF power amplifier (PA) into a single-chip transceiver is one of the most challenging works in implementing radio front-ends, which presents many advantages in handheld applications [1,2]. Especially, low-power efficiency enhancement (LPEE) techniques, considering the probability distribution function of the practical wireless communication environments, extend the battery lifetime...
