A dielectric duplexer which includes a dielectric block having a plurality of conductive through holes and an antenna excitation hole. On the outer surface of the dielectric block, an outer conductor, an input terminal, an output terminal, and an antenna terminal are provided. The input terminal, the output terminal, and the antenna terminal are separated from the outer conductor. The antenna terminal is electrically coupled with the antenna excitation hole. The absolute value of the reflection coefficient of at least one of the input terminal, the output terminal, and the antenna terminal is in the range of about 0.33 to about 1.00 in a passband, with a reference impedance of 50 OMEGA.
