Abstract

L'invention se rapporte à un filtre guide d'onde à cavités multiples rendant possible la réalisation des fonctions de transfert de filtre passe-bande par cavités couplées. Le filtre se compose d'un ensemble de cavités guides d'ondes en cascade 11, 12, 1N, chacune résonnant dans un premier et un second modes orthogonaux indépendants. En plus des vis 21, 22,.. 2N, réalisant les couplages intra-cavite, et des plaques de couplage 31, 32, 3(N-1), la plaque terminale 5N est une plaque réflectrice, la plaque 51 comportant des fentes d'entrée et de sortie. L'invention s'applique à tous filtres passe-bande.
