Abstract

L'invention concerne un filtre électrique de branchement Il comporte deux filtres diélectriques comprenant chacun, dans un boîtier métallique, un dispositif d'excitation, une tige d'excitation et au moins un résonateur diélectrique entre le dispositif d'excitation et la tige d'excitation. Le réglage de chaque filtre diélectrique est effectuée au moyen d'une vis qui modifie la capacité entre le boîtier et la tige d'excitation. L'invention s'applique notamment au couplage entre une antenne et un émetteur-récepteur radioélectrique
