Artech House announced the publication of "High-Efficiency Load Modulation Power Amplifiers for Wireless Communications" by Zhancang Wang. 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 efficiency enhancement.

Passive load impedance tuner design, dynamic load modulation PA, active load modulation PA, Doherty PA and Chireix 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 and concurrent multiband dynamic load amplifiers, topology selection, design procedures and network output. This book presents the evolution of classical load modulation PA topologies in order to meet new challenges in the field.

"High-Efficiency Load Modulation Power Amplifiers for Wireless Communications" is available now from Artech House, a leading publisher of books for professionals in high-technology industries, at
