METHOD FOR SHARING UP LINK AND DOWNLINK OF WIBRO REPEATER USING FOR TIME DIVISION DUPLEX

摘要

A upturn of a portable Internet relay using a TDD mode and a down link sharing method are provided to reduce generation heat by using high power amplifier for improving space by using modules inside the relay as single module. The signal received from a base station is received to a donor antenna(1) by being inputted to a first surge coupler BPF(Band Pass Filter)(2) of a first BPF(Band Pass Filter) part(16). The signal passing is input to the down-link switch LNA(Low Noise Amplifier) part(3). The predetermined amount of the downlink signal from the base station is coupled and the RF(Radio Frequency) signal is inputted to the SDM(Sync Detector Module)(14). If the signal is amplified to LNA of the down-link switch LNA part to the low noise, the first down-link switch LNA is off.
