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 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.
