PURPOSE: A transceiver for a mobile communication network base station system is provided to compose the first and second modules for selectively using a transmission diversity and use the second module as a random path when failure is generated in a transmission-side path in case that the transmission diversity is not used. CONSTITUTION: A back-board(100) connects to a cable, for supplying a power and performing an interface with a BSC(Base Station Controller). A TRC(TRansceiver Card)(200) connects to the back-board(100), and selectively uses a transmission diversity. The TRC(200) has the first module(210) for mounting a PCB having two reception paths and one transmission path, and the second module(220) for mounting a PCB having the other transmission path. |
