Commonly used approaches for the design of power amplifiers (PAs), specifically in the microwave and millimeter‐wave frequency range, are reviewed and discussed. Measurement‐based techniques are compared with CAD‐based approaches, stressing their relative strengths and weaknesses. Simplified techniques are also discussed, particularly addressing the preliminary evaluation of the power capabilities of a given device and to gather physical insight into the power‐generating mechanisms. Finally, harmonic tuning for high‐efficiency power amplifier design is outlined, together with its basic application rules. © 2004 Wiley Periodicals, Inc. Int J RF and Microwave CAE 14: 493–506, 2004.
