<P>PROBLEM TO BE SOLVED: To provide a radio communication device having high reliability. Ž<P>SOLUTION: The radio communication device is provided with a first mixer 12 for converting a received signal input from an antenna for receiving radio waves into a plurality of different intermediate frequencies, and a first internal signal generator 13. The radio communication device is also provided with channel filters 14-1 and 14-2 for discriminating the received signals converted into the plurality of different intermediate frequencies in correspondence with respective frequencies. Further, it is provided with a plurality of second mixers 15-1 and 15-2 in which frequency differences to the received signals converted into a plurality of different intermediate frequencies become similar, and second internal signal generators 16-1 and 16-2. A local oscillation signal generating means converts signals discriminated in correspondence with the respective frequencies into a second intermediate frequency of the same frequency and receives the second intermediate frequency.
