Compression Phenomena in Hard-Saturated Microwave Amplifiers

Abstract

An earlier report from this laboratory described the anomalous compression of a weak signal by a stronger one in a hard-saturated FET amplifier. It was shown that the amplifier's compression characteristics were not consistent with the conventional theory of hard limiters. This report recasts the hard-limiter theory in terms of a Volterra series, and shows that the previously unexplained compression characteristics are to be expected in hard-saturated multistage amplifiers. Keywords: Desensitization; Intermodulation distortion; Nonlinear systems; Saturation; Volterra-series analysis.
