Abstract

L'invention concerne un circuit de protection fonctionnant dans la bande des micro-ondes, dont l'une des diodes semi-conductrices du type Schottky est utilisée lors des contrôles de fonctionnement, comme source de bruit. Elle consiste à polariser l'une des diodes en tension jusqu'au régime d'avalanche. Elle est applicable aux amplificateurs pour télécommunications.
