ABSTRACT:
A ceramic filter can be made small in size by forming one or more strip-line resonators (5) on a side surface (4) of the ceramic resonator, the side surface additionally having contact and coupling electrodes which can be formed using the same mask as for the strip-line resonators. The strip-line resonators (5) produce zeros in the transfer function of the filter and thereby increase the attenuation at a desired frequency, e.g. the image frequency.
