The design of 220GHz multi-section variable-period folded waveguide TWT

Abstract

High frequency characteristics of 220GHz folded waveguide slow wave structure were studied and a 220GHz three-section variable period folded waveguide TWT was designed. Compared with three-section uniform-period folded waveguide TWT and two-section variable-period folded waveguide TWT, three-section variable-period folded waveguide TWT had the highest output power and electronic efficiency.
