- - - SYSTEM FOR TRANSMITTING/RECEIVING RADIO FREQUENCY SIGNAL USING DUAL-INPUT DUAL-OUTPUT FILTER

摘要

The dual-input dual-multipoint using the filters on the output - initiates a radio frequency signal transmitting and receiving system of the band . Transmission system is a single-input single-output of the filter and a dual-input dual-output of a filter ; band pass filter (Band-Pass Filter, BPF), phase shifter (Phase Shifter, PS), a low noise amplifier (Low Noise Amplifier, LNA), power amplifier (Power Amplifier, PA), Balun (Balun)
