• Class C amplifiers conduct less
than 50% of the input signal and the
distortion at the output is high,
but high efficiencies (up to 90%) are
possible. Some applications (for
example, megaphones) can tolerate the
distortion. A much more common
application for Class C amplifiers is in RF
transmitters, where the
distortion can be vastly reduced by using tuned loads
on the amplifier stage.
• The input signal is used to
roughly switch the amplifying device on and off,
which causes pulses of current to flow through a tuned
circuit.
