Abstract

Bei dem kapazitiven Trennglied zur galvanischen Trennung eines Koaxialkabels [42] ist zusätzlich zu einem Trennkondensator [A] im Außenleiter ein Hochfrequenzfilter, vorzugsweise ein Tiefpaßfilter vorgesehen, mit dem die Abschirmeigenschaften des Trenngliedes wesentlich verbessert werden. Der Trennkondensator im Außenleiter kann Teil des Hochfrequenzfilters sein. Durch mehrere kaskadenartig ge­ schaltete Hochfrequenzfilter können die Dämpfungseigenschaften des Trenngliedes noch weiter verbessert werden.
