Abstract:
A dielectric duplexer comprising:a dielectric block; a plurality of inner-conductor-containing holes formed in the dielectric block, each hole having an inner conductor formed on the inner surface thereof, the inner-conductor-containing holes extending from one surface to another surface opposite thereto of the dielectric block; an outer conductor and an input/output terminal which are formed on the outer surface of the dielectric block, the input/output terminal being separated from the outer conductor; and at least one short circuited conductor formed between the plurality of inner-conductor-containing holes on a transmitter side and the plurality of inner-conductor-containing holes on a receiver side, said at least one short circuited conductor extending from one surface that is parallel to the axes of the inner-conductor-containing holes to another surface opposite thereto and conductively coupled to said outer conductor at both ends thereof.
