Abstract

L'INVENTION PORTE SUR UN FILTRE HYPERFREQUENCE REALISE EN GUIDE D'ONDES DE SECTION RECTANGULAIRE, A N CAVITES RESONNANTES COUPLEES PAR DES IRIS A UN TRONCON DE GUIDE D'ENTREE, ENTRE ELLES ET A UN TRONCON DE GUIDE DE SORTIE. LE GRAND COTE DE SECTION DE CHACUNE DES CAVITES EST DE LONGUEUR SUPERIEURE A CELLE DU GRAND COTE DE SECTION DES TRONCONS DE GUIDE D'ENTREE ET DE SORTIE ET EST DEFINI POUR QUE LA DIMENSION DE CHAQUE IRIS SOIT LA PLUS PETITE POSSIBLE. ON REALISE AINSI DES FILTRES PASSE-BANDE A REPONSES PARASITES REDUITES, ET A FREQUENCE CENTRALE VARIABLE PAR SIMPLE MODIFICATION DES LONGUEURS ELECTRIQUES DES CAVITES.
