Title
(EN) MULTIPACTION-PROOF WAVEGUIDE FILTER
(FR) FILTRE DE GUIDE D’ONDES RÉSISTANT À UNE DÉCHARGE AUTO-ENTRETENUE
Abstract
(EN) A multipaction-proof waveguide filter includes a main cavity and a number of corrugations extending from the main cavity. The main cavity includes corrugation interconnect regions between the plurality of corrugations. The corrugation interconnect regions include sloped surfaces, and the corrugations include flared nonparallel sidewalls. Due to the introduced sloped surfaces and flares, an increased Q is achieved, improved roll off is observed and multipaction risks are mitigated.
(FR) Filtre de guide d'ondes résistant à une décharge auto-entretenue, comprenant une cavité principale et un certain nombre d'ondulations s'étendant à partir de la cavité principale. La cavité principale comprend des régions d'interconnexion d'ondulation entre la pluralité d'ondulations. Les régions d'interconnexion d'ondulation comprennent des surfaces inclinées, et les ondulations comprennent des parois latérales évasées non parallèles. En raison de l'introduction des surfaces inclinées et des évasements, une augmentation de Q est obtenue, une élimination améliorée est observée, et les risques de décharge auto-entretenue sont atténués.
