摘要： A radio communication apparatus, a transmitter apparatus and a receiver apparatus that are capable of dealing with a plurality of signal waves. The radio communication apparatus has a millimeter wave transmitter (15) and a millimeter wave receiver (29). The millimeter wave transmitter (15) includes a multiplexing circuit (1), a millimeter wave up-converter (4) and an antenna (3). The millimeter wave receiver includes an antenna (31), a millimeter wave down-converter (32) and an output processing circuit (45). User-only signal waves are modulated by modulator circuits (121-124) such that they are located between the terrestrial waves and the satellite waves. The modulated signal waves are multiplexed in the intermediate frequency band, then converted into a millimeter wave band, and then transmitted. On the receiver side, the multiplexed waves are frequency down-converted, then separated, and then demodulated.
