Study and evaluation of the calculation level for intermodulation products in a traveling wave tube simultaneously amplifying two or more carriers
Abstract
A mathematical model of a travelling wave tube (TWT) is presented, for calculating the levels of intermodulation products, principally those of 3d order, when the tube is amplifying simultaneously two or more carriers, unmodulated or modulated is FM or PM. The model takes into account both the effect of non-linearity and the effect of conversion of amplitude to phase modulation. In short, this work takes into account the AM-PM conversion effect not computed by Sevy.
