<p>The present invention provides a dielectric filter and a dielectric duplexer (20), each including a plurality of dielectric resonators (22a - d, 23a -d, 24). The dielectric filter and the dielectric duplexer (20) each comprising: a dielectric block (21) having a first surface (26) and a second end surface opposite to each other; at least three resonator holes (22c, 22d, 24) passing through the first end surface (26) to the second end surface of the dielectric block (21); inner conductors disposed on the inner wall surfaces of the resonator holes (22a - d, 23a - d, 24); an outer conductor (36) disposed on the external surface of the dielectric block (21); the outer conductor (36) on the first end surface (26) of the dielectric block (21) being separated into an inner part (41) and a peripheral part (42) by a nonconductive portion (43); the inner part (41) including the openings of at least three (22c, 22d, 24) of the resonator holes (22a - d, 23a - d, 24) adjacent to each other; a peripheral part (42) being arranged around the inner part (41); and the inner part (41) and the peripheral part (42) being connected by a microinductance-generating means (44). <IMAGE></p> |
