MONOLITHIC DIELECTRIC FILTER

摘要

PURPOSE: A monolithic dielectric filter is provided to improve an attenuation characteristic and to be easy to produce by eliminating a part of a metal film so as to expose a body. CONSTITUTION: In a monolithic dielectric filter consisting of a ceramic shintering body(10)and having an input/output terminal(15), a plurality of through holes(11,12) are formed in the monolithic dielectric filter. The plurality of through holes are in parallel each other, and are extended from one side of the shintering body to the other side opposed to the one side of the shintering body. A metal film is coated at a part of the shintering body. The part of the shintering body is placed at a side plane at which the input/output terminal is not formed and at an edge placed between the through holes.
