| Summary: | 碩士 === 國立臺灣科技大學 === 工程技術研究所 === 83 === The active device of a switching-mode power amplifier acts as
"switch" rather than "current source". The high voltage and
current of a transistor will not exist simulaneously,so the
collector(drain) efficiency is high. Three RF power amplifiers
are realized with collector efficiencies of 73%,78% and 64%
respectively at 105MHz/2W and 470MHz/3W. They are achieved by
class D and class E techniques. The design rules and
implemeneation procedures are presented in detail.
