Amplifier distortion produces a dilation of the spectrum of the input signal (" spectralregrowth ") which causes interference to communications in adjacent channels.

This paper describes a new high power RF amplifier's IMD signal envelope detection method and compare technology, which is used to detect and estimate the RF spectralregrowth.
