Abstract :
Power balance considerations will be discussed, stressing the relevance of the power dissipated at harmonic frequencies. The high frequency operation of two different strategies for high efficiency PA design will be considered, Class E and Class FG respectively, and their performances compared by means of design examples performed on a single-stage power amplifier operating @ 5 GHz.
