Abstract

L'invention concerne les filtres accordables à plusieurs résonateurs portés par un tronçon de guide d'ondes. Elle consiste à remplacer les plongeurs de réglage des divers résonateurs par une lame unique dont on règle l'enfoncement au moyen d'une vis micrométrique. L'invention est applicable aux télécommunications au moyen d'ondes hyperfréquence.
