Abstract

a. Impédance hyperfréquence ajustable commandée par une tension. b. Structure semi-conductrice d'un type unique (n de préférence) associée à deux contacts ohmiques dont la densité de porteurs et les dimensions géométriques sont choisies pour que la tension de commande couvrant la gamme d'utilisation, le champ dans la structure passe par la valeur critique pr correspondant à la saturation de la vitesse des porteurs et reste inférieur à la valeur provoquant l'avalanche. c. Applications diverses aux circuits hyperfréquence.at. Adjustable microwave impedance controlled by voltage. b. Semiconductor structure of a single type (preferably n) associated with two ohmic contacts whose density of carriers and geometric dimensions are chosen so that the control voltage covering the range of use, the field in the structure passes through the critical value pr corresponding to the saturation of the speed of the carriers and remains lower than the value causing the avalanche. vs. Various applications to microwave circuits.
