Abstract
A dielectric duplexer includes a substantially-rectangular-parallelepiped-shaped dielectric block. The interior of the dielectric block includes inner-conductor-formed holes containing inner conductors. An outer conductor is formed on the substantial entirety of an exterior surface of the dielectric block. Input/output electrodes and antenna input/output electrodes are formed at predetermined positions. Thus, the dielectric block is provided with a band eliminate filter and a band pass filter. A C-L-C &pgr;/2 phase circuit in which C, L, and C are arranged in the shape of the letter &pgr; is provided between an antenna and the antenna input/output electrode of the band eliminate filter, and the antenna is connected to the antenna input/output electrode of the band pass filter.
