Abstract
L'invention concerne un filtre de bande de fréquence. Le filtre de bande de fréquence selon l'invention comporte une seule ligne coaxiale 1, séparée en plusieurs cavités résonnantes élémentaires C1 , C2 , ... Cn- 1, Cn par des pistons P1 ... Pn-1, Pn, déterminant les noeuds de tension du système d'ondes stationnaires établi dans la ligne. Les pistons assurent en plus du cloisonnement des cavités, leur couplage et leur accord en fréquence. Application aux amplificateurs de puissance UHF et VHF équipés de tubes à grilles et au filtrage de l'énergie HF, large bande, fournie par des montages à semi-conducteurs.
