Abstract
The present invention provides a radio communication device, a transmitter and a receiver capable of handling a plurality of signal waves. A radio communication device has a millimeter-wave transmitter () and a millimeter-wave receiver (). Millimeter-wave transmitter () includes a multiplexing circuit (), a millimeter-wave up-converter () and an antenna (), and the millimeter-receiver includes an antenna (), a millimeter-wave down-converter () and an output processing circuit (). The signal waves dedicated to the user are modulated by a modulation circuit (to) so as to be allocated between the ground broadcast waves and satellite broadcast waves. The frequencies are multiplexed in an intermediate frequency band, after that, the multiplexed frequencies are converted into a millimeter-wave band and the resultant is transmitted. On the reception side, the multiplexed waves are down-converted, separated to signal waves and demodulated.
