Signal-to-Intermodulation Noise in Biased Limiting Amplifiers

This paper summarizes 1) harmonic signal output for a variety of class C power amplifier models and 2) other biased amplifier configurations when the input consists of an arbitrary number of carriers plus noise; it also demonstrates signal suppression and/ or enhancement in the class C amplification process for several signal sets and amplifier models, and it develops expressions for output signal-to-intermodulation noise ratio if the input consists of a large number of equal amplitude carriers. Results are given in tabular form.
