DIELECTRIC DIPLEXER COMPRISING RESONATOR AND COMMUNICATION DEVICE COMPRISING THE SAME

摘要

PURPOSE: A resonator type dielectric diplexer and a communication device including the same are provided to complement a narrow bandwidth of the dielectric diplexer by implementing one side band with a low pass filter. CONSTITUTION: A first resonator of a resonator type dielectric diplexer(200) includes 1-1 to 1-4 resonators(13a-13d). A low pass filter pattern includes a first input and output pattern(31), a second input and output pattern(32) and a first to a fifth inductor patterns. The low pass filter pattern includes 1-1 to 1-4 capacitor patterns(42a-42d) respectively connected to the 1-1 to 1-4 resonators.
