Abstract

L'invention concerne un circulateur à guides d'ondes comportant au moins trois guides d'ondes et une section centrale. Les guides d'ondes sont interconnectés dans la section centrale. Un élément en ferrite est placé dans la section centrale. Le circulateur a un moyen permettant de magnétiser cet élément. Un des guides d'ondes renferme au moins un élément d'étranglement qui est conçu pour réduire les signaux de fuite émanant d'imperfections dans le circulateur.
