The present invention comprises a waveguide filter having a stepped transformer area on the input and/or output sides, with at least one band-stop filter composed of geometrically closely spaced stop elements integrated into this stepped transformer area. These features make it possible to build waveguide filters with a high edge steepness and a short overall length.
L'invention concerne un filtre à guides d'ondes comportant côté entrée et/ou côté sortie une région de transformateur à gradins (1, 3) dans laquelle est intégré au moins un coupe-bande (4, 5) constitué d'éléments de blocage (41, 42, 43; 51, 52, 53) successifs à géométrie compacte. On obtient ainsi des filtres à guides d'ondes présentant des pentes de signal élevées et une longueur totale réduite.
