Abstract

Abstract Translated from French L'invention concerne les oscillateurs à très haute fréquence et à grande stabilité en fonction de la température, utilisant un transistor couplé par une ligne de transmission du type microbande avec un résonateur diélectrique à très faible coefficient de température. L'oscillateur selon l'invention comporte un transistor (10) qui peut être soit à effet de champ, soit du type bipolaire, et un substrat (1) isolant métallisé sur une face formant plan de masse (4), ce dernier débordant le substrat (1) en un point voisin de deux lignes (2, 3) de transmission gravées sur la face du substrat (1) opposée au plan de masse (4), le transistor (10) étant soudé sur un ressaut (41) du bac formant plan de masse (4). Application à la réception des micro-ondes diffusées par satellite terrestre. The invention relates to very high frequency oscillators with high temperature stability, using a transistor coupled by a microstrip type transmission line with a dielectric resonator with a very low temperature coefficient. The oscillator according to the invention comprises a transistor (10) which can be either field effect or of the bipolar type, and an insulating substrate (1) metallized on a face forming a ground plane (4), the latter extending beyond the substrate (1) at a point close to two transmission lines (2, 3) etched on the face of the substrate (1) opposite the ground plane (4), the transistor (10) being soldered on a projection (41) of the tank forming ground plane (4). Application to the reception of microwaves broadcast by terrestrial satellite.
