Abstract
L'invention concerne un dispositif pour affaiblir des ondes parasites de cavité dans un tube électronique à haute fréquence. Dans ce dispositif, qui comporte une cathode 1, une grille 2, une anode 3, une bague de court-circuit 4, un élément de guide d'onde 5 et accouplé à la cavité du tube électronique, et l'élément de guide d'ondes 5 comporte une couche de résistance 7 de forte valeur ohmique et résistance élevée de cette couche est transformée, par l'élément de guide d'ondes 5, en une résistance de faible valeur pour les ondes perturbatrices de cavité devant être affaiblies, au niveau de la cavité du tube électronique. Application notamment aux tubes électroniques d'émetteurs à haute fréquence.
