Efficiency enhancement solutions for an original linear green RF transmitter

Abstract

Designing linear transmitters became mandatory to cater with high data rates applications and this trend is increasing, especially with 5G. This leads to a huge amount of energy consumption and important environmental challenges. For RF design point of view, the issue is improving energy efficiency, especially in user mobile equipment. This work proposes an original linear green RF transmitter system based on efficiency enhancement technique at the transmitter and linearization at the receiver in an uplink radio cognitive context. Measurement results are performed and validate the concept.
