High-Efficiency Load Modulation Power Amplifiers for Wireless Communications

by Zhancang Wang (Author)

This cutting-edge resource presents a complete and systematic overview of the practical design considerations of radio frequency (RF) high efficiency load modulation power amplifiers (PA) for modern wireless communications for 4G and beyond. It provides comprehensive insight into all aspects of load modulation PA design and optimization not only covering design approaches specifically for passive and active load modulation operation but also hybrid with dynamic supply modulation and digital signal processing algorithms required for performance enhancement.

Passive load impedance tuner design, dynamic load modulation PA, active load modulation PA and Doherty PA design for efficiently enhancement are explained. Readers find practical guidance into load modulation PA design for bandwidth extension, including video bandwidth enhancement techniques, broadband dynamic load amplifiers, topology selection, design procedures, and network output. This book presents the evolution and integration of classical load modulation PA topologies in order to meet new challenges in the field

Review
Zhancang Wang's High-Efficiency Load Modulation Power Amplifiers for Wireless Communications (9781608079872, $179.00) reviews the designs of radio frequency high effiency load modulation amplifiers for wireless systems, and covers all kinds of details for PA design and optimization that engineers must have. Readers receive technical discussions packed with charts and graphics, math, and surveys of different configurations and their advantages, including measurement methods for dynamic load amplifiers and discussions of various PAs and their design procedures. No college-level reference holding should be without these important discussions. –Midwest Book Review, September 2017

This book is an excellent starting platform for entering the exciting world of high-efficiency radio transmitter design. –Dr. Andrei Grebennikov, author of 10 books dedicated to RF and microwave circuit design
