Abstract

1371933 UHF band-pass filters LICENTIA PATENTVERWALTUNGS GmbH 10 Jan 1972 [26 Jan 1971] 1003/72 Heading H1W A tunable UHF band-pass filter comprises two coupled resonant lines 2, 3 separated by a partition 4, the coupling consisting of an inductive tab 11 and capacitors 12, 13 connected between the tab and the lines. The resultant T-section LC coupling circuit causes an increase in coupling at the upper end of the frequency range. The tab 11 may lie in the plane of the partition 4 or may be bent out of this plane. One of the capacitors may be of the feedthrough type mounted in the partition 4.
