Abstract

Titre: RESONATEUR AVEC CRISTAL LIQUIDE ET BULLE DE GAZ L’invention concerne un élément diélectrique (7) pour un résonateur (2) ainsi qu'un résonateur correspondant (2). L'élément diélectrique (7) comporte une première chambre (50) et une seconde chambre (60), qui sont reliées fluidiquement l'une à l'autre avec un canal de liaison (70). Un cristal liquide est contenu dans la première chambre (50), un gaz est contenu dans la seconde chambre (60). Des variations de volume du cristal liquide peuvent être compensées par une variation de volume du gaz, parce que le cristal liquide peut se déplacer dans le canal de liaison. De cette façon, un tel résonateur peut être utilisé sur des plages de température fortement fluctuantes, sans que cela nécessite une autre compensation pour des variations de volume du cristal liquide dues à la température. De même, l'élément diélectrique (7) peut être hermétiquement fermé pour terminer l'opération de fabrication. Fig. 1
