In this thorough overview, Mihai Albulet presents a full account of RF amplifiers and shows that understanding large-signal RF signals is simply a matter of understanding basic principles and their applications. In addition to discussing the basic concepts used in the analysis and design of RF power amplifiers, detailed mathematical derivations indicate 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.
