とする誘電体共振器型フイルタ分波器。[Claims for Utility Model Registration] A transmission signal from a transmission signal input terminal is guided to an antenna terminal via a band elimination filter, a first band filter consisting of a dielectric resonator, and a low-pass filter, and from this antenna terminal. a received input signal through the low-pass filter and a second band-pass filter to a received signal output terminal, and the connection between the low-pass filter and the second band-pass filter is connected to the first band-pass filter. In the dielectric resonator type filter duplexer in which the transmission output side terminal of the filter is used as a relay terminal, a connection line from the first band filter to the low pass filter, and a connection line from the first band filter to the low pass filter are provided. A dielectric resonator type filter duplexer, characterized in that connection lines leading to a second band filter are placed in close contact with each other and parallel to each other in a transmission output side terminal area of the first band filter.
