A dielectric diplexer is disclosed. The dielectric diplexer according to the present invention comprises: a dielectric block having a plurality of resonance holes formed to penetrate from a first surface to a second surface, which faces the first surface; inner patterns formed on inner surfaces of the resonance holes, respectively; a grounding pattern formed on at least a part of the outer surface of the dielectric block; first to third input/output patterns formed on the dielectric block; a low pass filter unit; a band pass filter unit; and a metal cover, which is electrically connected to the grounding pattern, and which faces the first surface while being spaced therefrom, wherein the low pass filter unit comprises a first resonance hole positioned on one side of the dielectric block among the plurality of resonance holes, a first inductance pattern formed on the first surface and connected to the first input/output pattern and to the inner pattern of the first resonance hole, a second inductance pattern formed on the first surface and connected to the second input/output pattern and to the inner pattern of the first resonance hole, and a first capacitance pattern formed on the second surface, connected to the inner pattern of the first resonance hole, and spaced from the grounding pattern, and the band pass filter unit comprises a second resonance hole formed on the other side of the dielectric block among the plurality of resonance holes and a second capacitance pattern formed on the first surface, connected to the inner pattern of the second resonance hole, and spaced from the grounding pattern and from the second and third input/output patterns. |
