Dielectric filter, dielectric duplexer, and transceiver

摘要

The present invention provides a dielectric filter and a dielectric duplexer, each including a plurality of dielectric resonators. The dielectric filter and the dielectric duplexer each comprising: a dielectric block having a first surface and a second end surface opposite to each other; at least three resonator holes passing through the first end surface to the second end surface of the dielectric block; inner conductors disposed on the inner wall surfaces of the resonator holes; an outer conductor disposed on the external surface of the dielectric block; the outer conductor on the first end surface of the dielectric block being separated into an inner part and a peripheral part by a nonconductive portion; the inner part including the openings of at least three of the resonator holes adjacent to each other; a peripheral part being arranged around the inner part; and the inner part and the peripheral part being connected by a microinductance-generating means.
