Abstract
A dielectric filter utilizing a plurality of serially coupled resonators having attenuation maximums at the lower side or higher side, or both, of a pass band frequency region. The filter may include an input element which is coupled with both of a first resonator and a second resonator, and may also include an output element which is coupled with both the last and the next-to-last resonator. In the dielectric filter, it is not necessary to provide an external wire connection to generate such attenuation maximums.
