Abstract

L'invention concerne un résonateur accordable en fréquence comprenant : un boîtier, dont la surface d'un côté est ouverte, et qui comporte un espace de logement en son sein ; un couvercle qui recouvre la surface ouverte du boîtier ; un élément de résonance contenu dans l'espace de logement du boîtier ; une vis d'accord agencée sur la partie supérieure de l'élément de résonance à travers le couvercle ; un matériau isolant intercalé entre le couvercle et la vis d'accord de manière qu'il n'y ait aucun contact conducteur entre la vis d'accord et le couvercle ; et un élément capacitif, dont la borne située d'un côté est en connexion conductrice avec la vis d'accord, dont la borne située de l'autre côté est en connexion conductrice avec le couvercle, et qui possède une capacité. Le résonateur accordable en fréquence selon la présente invention comporte un élément capacitif supplémentaire qui lui est connecté, en plus d'une vis d'accord pour l'accord en fréquence, ce qui permet d'augmenter davantage la quantité de modification de la fréquence qui est accordée, et un accord en fréquence peut également être effectué par un signal de commande externe, ce qui permet d'effectuer un accord en fréquence plus efficacement. En outre, le résonateur accordable en fréquence selon la présente invention comporte un condensateur équivalent, qui est formé par la vis d'accord, et un condensateur supplémentaire, qui est destiné à l'accord en fréquence, formés en série pour que la capacité puisse être réglée d'une manière plus détaillée, ce qui permet d'atténuer la sensibilité d'accord d'un filtre haute fréquence. De plus, le résonateur selon la présente invention permet de rendre léger et compact le filtre haute fréquence.
