BAND-PASS FILTER

摘要

The invention relates to a band-pass filter which has a pass band with a comparatively large pass-band width while at the same time presenting comparatively steep sides leading towards the stop-band and little damping in the pass band. The band-pass filter comprises three parallel LC members (LP1, CP1; LP2, CP2; LP3, CP3) one of which is positioned between a band-pass filter inlet (IN) and a band-pass filter outlet (OUT) while the other two are connected with one of their connectors to a fixed reference potential (P).
