Abstract :
The phase velocity dispersion of a traveling wave tube circuit is a major design parameter of a wide band TWT. The phase velocity dispersion determines the degree of variation in the electron bunching process as a function of frequency and as a result determines the frequency dependence of the gain, the AM/PM, the linearity, the harmonic power and tolerance to beam voltage changes.
