Microwave Power Amplifiers are discussed, focusing mainly on solid-state implementations. Starting with an introduction on solid-state and vacuum device power generating capabilities and solid-state active realization technologies and materials, this article introduces and defines the basic quantities defining and characterizing a microwave power amplifier. The basic concepts of operating class and the relevant expected performances are addressed, including reference cases. Power balance considerations are inferred and high-efficiency power amplifier design techniques are detailed, including both harmonic tuning approaches and switched-mode amplifier schemes. Measurement-based approaches (load pull) and computer-aided design techniques are also discussed.
