'[This] Handbook is a comprehensive reference for RF and microwave power amplifiers. It includes both theory and practice as well as a variety of different applications. Often overlooked supporting topics such as CAD, thermal design, and reliability are treated in depth. John Walker has put together an outstanding team of authors, each of whom is well qualified to address his topic. Finally, I like the way it is organized with separate chapters for three types of RF-power transistors (silicon, GaAs, and GaN/SiC) and separate chapters for amplifiers of different frequency types (HF/VHF/UHF, microwave, and IC).'
