BAND PASS FILTER ABSTRACT OF THE DISCLOSURE In a band pass filter having a plurality of quarter- wavelength resonators, at least two of the quarter-wavelength resonators are substantially shielded from each other by a partition wall. These two resonators are electrically connected to each other through a line insulated from the casing, so as to improve the cut off characteristic of the filter, namely to cut off the applied signal in a high frequency region of the band being filtered more rapidly than in a low frequency region.
