ABSTRACT:
Resonator holes are formed extending one to the other of a pair of opposing end surfaces of a dielectric block, and inner conductors are formed on inner peripheral surfaces of resonator holes respectively. On an outer surface of dielectric block, a pair of input/output electrodes and one antennal electrode are formed, and expect these regions, an outer conductor is formed. By the coupling of two resonators corresponding to the resonator holes, a transmitting filter is provided, and by two resonators corresponding to resonator holes, a receiving filter is formed.
