HIGH POWER S-BAND ELECTRON BEAM PHASE SHIFTER TECHNIQUE
Abstract
This report is a summary of work to design and develop a breadboard model of a 100 kilowatt S-band phase shifter. The phase shifter utilizes an electron beam of input power much lower than the microwave power transmitted through the structure. The variable current beam interacts with the slow-wave structure to perturb the propagation constants of the combined beam and slow- wave structure system. A model was constructed and operated at a 100 kilowatt power level. The performance of this model was limited by low beam current; however, measured performance was in excellent agreement with theoretical values. From this work it can be concluded that a device in S-band operating at a 100 kilowatt power level and providing 360 degrees variation in Phase shift is feasible. The physical size and relatively high insertion loss of such an electron beam phase shifter tend to make it unattractive in comparison with recently developed solid-state phase shifters.
