Creation of powerful broadband low-voltage small-sized grid-controlled pulse TWT over decimetre waves

Abstract

Decrease of anode voltage, mass, and dimensions of powerful pulse traveling-wave tube (TWT) with grid modulation, as well as broadening the operating frequency range of signals to be amplified, is achieved by the increase of a perveance of an electron beam formed by the original three-grid electron gun. The features of focusing the high-perveance electron beam by PPM system are shown. Main parameters of such TWTs are presented.
