Abstract: 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.

Abstract: A down link sharing up-down converter module for a portable internet relay of a TDD mode for improving the performance of the relay is provided to use one relay apparatus in the mode which is comprised of a relay configuration. If a down-link RF(Radio Frequency) signal is input to a down-link input port(1), the downlink sink signal is inputted to a sink down-link signal of computer(26). A first down-link and a downstream indistinguishable RF switch(4) are connected to a downlink path. The signal passing through the upturn of up-link and the first down-link, and the downstream distinguish RF switch is inputted to the coupler(5) for detecting the input level. It is inputted through the switch connected to the sink down-link signal of computer signal to the downlink path to the detector(10).
