Article: Amplifier Alphabet Soup: Part II, Basics Of Power Amplifier Classes D, E, F And Inverse-F
By Bill Slade, Orban Microwave Products
Part I of this series summarized the operation of the classical limited conduction angle amplifier topologies (Class-A, AB, B, C). Switching amplifiers are given the class designators D, E, F and inverse F. Part II of this series will focus on a qualitative review of these amplifier class definitions as well as giving some explanation on where inefficiencies appear in each. Some of the advantages and disadvantages of each topology will be presented and the trade-offs will be briefly elaborated in an intuitive manner.
