Abstract/Description
-
Classes of operation of solid state power amplifiers are surveyed with an emphasis on high efficiency radio frequency applications. Classes A through H and S are covered, with the first three classes combined in a unified analysis. Time domain analyses of the switched-mode classes, D through S, include the effects of stray reactances, switch transition times, and load variations. For class E, a point of optimum operation is derived, and component values are determined assuming optimum...
Show moreClasses of operation of solid state power amplifiers are surveyed with an emphasis on high efficiency radio frequency applications. Classes A through H and S are covered, with the first three classes combined in a unified analysis. Time domain analyses of the switched-mode classes, D through S, include the effects of stray reactances, switch transition times, and load variations. For class E, a point of optimum operation is derived, and component values are determined assuming optimum operation. The multi-resonator and transmission line forms of class F are analyzed. In the last section, audio amplifier and modulator applications of classes G, H, and S are discussed. The characteristics of all the classes of power amplifiers discussed are summarized in a table at the end of the paper.
