Designers of RF power amplifiers have a new, comprehensive reference. In this thorough overview, Mihai Albulet presents a full account of RF amplifiers and shows that understanding large- signal RF circuits is simply a matter of understanding the basic principles and their applications. In addition to discussing fundamental concepts used in the analysis and design of RF power amplifiers, detailed mathemati-cal derivations show the assumptions and limitations of the presented results, allowing the reader to calculate their usefulness in practical designs. Covered are amplification classes, circuit topologies, bias circuits, and matching networks.
