CLASS E

Class E transmitters are high efficiency, reliable, solid-state transmitters. They are simpler to build than similar transmitters using vacuum tubes, and are significantly less expensive to both build and to operate. Class E is a switching mode of operation, and exhibits extremely linear modulation characteristics, making these amplifiers well suited for high quality, amplitude modulation. They are also very well suited for amplification of frequency modulation or other modes where linear amplification is not a requirement... One of the major goals of the class E project is to facilitate the construction, by Amateurs with only a modest background in construction, of a high power, good sounding AM transmitter using modern, readily available components and at a reasonable cost.
