RELAY TRANSMITTING AND RECEIVING APPARATUS

PROBLEM TO BE SOLVED: To provide a relay transmitting and receiving apparatus having a function to suppress interference in the transmitting and receiving apparatus because of sneaking of a transmitted wave or a received wave, radio wave interference between a transmitted signal and a received signal, and waveform distortion. SOLUTION: The relay transmitting and receiving apparatus 10 includes a base station side antenna 100 and a mobile station side antenna 200, i.e., the reception units which receive the first signal transmitted and received to/from a base station and the second signal transmitted and received to/from a mobile station, a base station side local oscillator circuit 306 and a mobile station side local oscillator circuit 307, i.e., the frequency conversion units which convert the frequencies of the first signal and/or the second signal so that the frequency of the first signal is different from that of the second signal, and a base station side antenna 100 and a mobile station side antenna 200, i.e., the transmission units which transmit the first signal and second signal generated by the base station side local oscillator circuit 306 and the mobile station side local oscillator circuit 307.
