Small-Signal Model for Inhomogeneous Helix Traveling-Wave Tubes using Transfer Matrices
Robert Marosi, Kasra Rouhi, Tarek Mealy +2
Abstract We introduce a practical method for modeling the small-signal behavior of frequency-dispersive and inhomogeneous helix-type traveling-wave tube (TWT) amplifiers based on a…
