Dielectric filter with attenuation poles.

摘要

The invention relates to a dielectric filter with attenuation poles. A first dielectric block or blocks (1) have a cut out portion and the cut out space is filled with a second dielectric block (6). A bypass pattern (7) is formed on the second dielectric block (6) and is capacitively coupled with two resonance elements formed on the first dielectric blocks (1). The dielectric filter is compact, and the position and intensity of attenuation poles can be freely designed and easily adjusted. <IMAGE>
