THE FEEDER SHARING DEVICE MINIMIZING INTERMODULATION SIGNAL

摘要

PURPOSE: A feeder sharing device minimizing inter-modulation signal is provided to minimize the created PIMD(Passive Inter-modulation Distortion) phenomenon in the sharing of the communications signal of the WIBRO mode and WCDMA mode. CONSTITUTION: A first distributor(110) falls the power level of the WCDMA signal. A second distributor(120) falls the power level of the WIBRO signal. A diplexer(150) receives a WCDMA signal outputted through the first distributor and the WIBRO signal outputted through the second distributor. The diplexer unites the WCDMA signal and WIBRO signal. The diplexer shares a signal in a state with a minimum PIM signal generation power.
