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.
The goal of this site is to present a working, practical tutorial on
class E transmitters (a complete explanation of class E is included),
and to provide sufficient information to allow someone with reasonable
radio experience, technical skills and knowledge to construct a working
class E transmitter or design a transmitter using similar RF and
modulation methods. The designs presented here have been reproduced
many times and are proven and reliable.
Complete schematics [unless otherwise noted] of real, working
transmitters (along with pictures and technical explanations) that I
have personally built and are using on the air daily are included. They
are accurate representations of what is (or was) in use on the air at
that time. The photos show various components and construction methods
