Atténuateur fixe de faible puissance

Dans certains modules ou systèmes RF, l'atténuateur réduit la puissance de sortie sans altérer la forme d'onde ni les données lorsque cette puissance est trop élevée et risque d'endommager le système ou l'équipement. L'atténuateur améliore aussi l'adaptation d'impédance et la fiabilité du circuit, et permet d'ajuster les niveaux entre deux circuits ou dispositifs différents. Psatek fournit des atténuateurs fixes de 1 W à 500 W, de DC à 67 GHz, avec de nombreux connecteurs au choix. Contactez l'équipe commerciale (sales@psatek.com) pour un devis.
