This guide to the theory and practice of RF power amplifier (PA) design for modern communications systems aims to help readers tackle PA design with confidence and save time in determining the cause of malfunctioning hardware. The book explores a unified approach to the classification of higher amplifier modes based on overdrive considerations. The text contains a complete survey of RF PA efficiency enhancement and linearization techniques and aims to help the reader design suitable matching networks which provide correct fundamental harmonic terminations for conventional high efficiency PA modes. It also provides an understanding of the class D, E and F modes and their feasibility at microwave frequencies and uses envelope simulation techniques to analyze the effects of distortion in overdriven PAS. Finally, the text discusses the maintenance of high efficiency operation at low points in an amplitude modulated signal envelope including detailed coverage of the Doherty, Chireix and Kahn techniques, it explores the possibilities and limitations of linearization methods and analyzes PA stability and oscillation problems.

This volume builds on the author's previous work, "RF Power Amplifiers for Wireless Communications", offering experienced engineers a more in-depth understanding of the theory and design of RF power amplifiers. A useful reference tool for RF-, digital- and system-level designers, the book includes discussions on the most critical topics for professionals in the field, including envelope power management schemes and linearization. This book should be of interest to RF- and microwave-design engineers in wireless communications, as well as digital- and system-level engineers in satellite communications.

Reviewing the previous edition, "IEEE Microwave Magazine" boasted, "anyone designing power amplifiers will find this book thought provoking and useful." Professionals in the field agreed as the book went on to be one of our top-selling RF design titles. This extensively revised edition of "RF Power Amplifiers for Wireless Communications" offers practitioners a comprehensive, practical, and up-to-date understanding of how to tackle a PA (power amplifier) design with confidence and quickly determine the cause of malfunctioning hardware. Among the numerous updates, the Second Edition includes five new chapters on some of today's most important topics, such as class AB PAs at GHz frequencies; switching PA modes at GHz frequencies; signals, modulation systems, and PA nonlinearities; power amplifier bias circuit design; and load-pull techniques. Supported with nearly 200 illustrations, the book contains the most complete survey of RF PA efficiency enhancement and linearization techniques in a single volume.
