The present invention provides a solution for maintaining and improving the specifications of the conducted susceptibility of a microwave channel. The main advantage of the invention is to provide a significant attenuation of the parasite modulated signals (PAR4) conveyed in the microwave channels of microwave devices such as those integrated into satellites, by simply adding one or more 180° phase shifters (PHI) between the components (CRF1,CRF2) that do not have a sufficient conducted susceptibility performance. Consequently, the invention makes it possible to omit certain elements in charge of attenuating parasitic signals and generally integrated in the power supplies and other DC/DC converters (ALIM1) present in all current microwave apparatuses.

La présente invention consiste en une solution à la tenue et à l'amélioration des spécifications sur la susceptibilité conduite d'une chaîne hyperfréquence. Elle a pour principal avantage de rendre possible une atténuation importante des signaux modulés parasites (PAR4) portés dans les chaînes hyperfréquences de dispositifs hyperfréquences tels que ceux qu'on intègre à des satellites en ajoutant simplement un ou plusieurs déphaseurs (PHI) de 180 ° entre les composants (CRF1,CRF2) ne présentant pas une performance de susceptibilité conduite suffisante. L'invention permet en conséquence de s'affranchir de certains éléments chargés de l'atténuation des signaux parasites généralement intégrés aux alimentations et autres convertisseurs DC/DC (ALIM1) présents dans tous les équipements hyperfréquences actuels.
