PURPOSE: A relaying device of a wireless communication system is provided to relay each high frequency signal between a base station and a terminal through a simple circuit device, so as to simplify an entire system. CONSTITUTION: A local oscillating frequency generator(64) supplies local oscillating frequencies. A down converter(1000) receives many high frequency signals to mix the high frequency signals with the local oscillating frequencies, and converts the high frequency signals into low frequency signals to supply each intermediate frequency(IF). A distributor(130) distributes each of the IFs to many paths. A frequency selector(134) passes self IFs only among each of the IFs. A coupler(154) couples the self IFs with one path. An up converter(2000) receives each of the IFs from the coupler to mix the received IFs with the local oscillating frequencies, respectively, and converts each of the IFs into high frequencies to supply the original high frequency signals.
