ABSTRACT:
A duplex dielectric filter is disclosed in which plural elements of the filter are merged into a single element to thereby simplify the manufacturing process and product handling, and automatize assembly. The conventional three separate shunt capacitors are simplified into a single dielectric substrate. A brass shim which was conventionally inserted between the shunt capacitors and the dielectric substrate to adjust the height of the shunt capacitors is eliminated. A dielectric substrate having load capacitors is extended to substitute for the brass shim. A through hole is formed through electrode patterns which are formed on both sides of the dielectric substrate to connect an input terminal to the shunt capacitors.
