Development of W band folded waveguide traveling wave tube

摘要

A W band folded waveguide Traveling Wave Tube that adopts horseshoe-shaped attenuator and a periodic step-tapering folded waveguide slow wave structure is reported in this paper. In this Traveling Wave Tube, Reflection from severability was effectively reduced and self-oscillation was depressed, and also electronic efficiency is raised by about 1.5~2% comparing with uniform periodic folded waveguide Traveling Wave Tube.
