Festes Dämpfungsglied, niedrige Leistung

In manchen Modulen oder HF-Systemen kann ein Dämpfungsglied die Ausgangsleistung reduzieren, ohne die Signalform oder die Daten zu stören oder zu verändern, wenn die Ausgangsleistung zu hoch ist und das System oder die Geräte beschädigen könnte. Ein Dämpfungsglied verbessert nicht nur die Impedanzanpassung und sichert die Zuverlässigkeit der Schaltung, sondern kann auch zur Pegelanpassung zwischen zwei unterschiedlichen Schaltungen oder Geräten eingesetzt werden. Psatek liefert feste Dämpfungsglieder von 1 W bis 500 W im Frequenzbereich von DC bis 67 GHz mit verschiedenen Anschlüssen zur Auswahl. Bitte kontaktieren Sie das Vertriebsteam (sales@psatek.com) für ein Angebot.
