FILTER PACKAGE

摘要

A filter package comprises: a substrate; a plurality of resonators individually coupled to the substrate; and a metal circuit pattern patterned on the substrate. Each of the resonators includes: a body composed of a dielectric material, and having a through-hole formed in one direction; and a conductive layer coupled to a cross section coupled to the substrate from cross sections of both sides in the body and a wall of the through-hole.
