Abstract
An improved power amplifier is disclosed which is particularly useful with very high frequency (VHF) transceivers. The power amplifier includes a control loop configured to sense the input radio frequency signal and use that signal as a reference for comparison with the radio frequency output from the amplifier to control amplifier power output. The loop forces the amplifier's output radio frequency envelope to follow the input radio frequency envelope and thus produce a constant gain loop. A limiter in the loop forces the loop to produce a constant power output when the input signal exceeds a level set by the limiter.
