This method not only can achieve the distortionless envelopedetection of voltage flicker, but also can detect the time, frequency and amplitude of the signal accurately.
This paper describes a new high power RF amplifier's IMD signal envelopedetection method and compare technology, which is used to detect and estimate the RF spectral regrowth.
