PROBLEM TO BE SOLVED: To provide a mixing system capable of mixing two signals duplicate in frequency. SOLUTION: A 1st input signal S(CS-IF) is frequency-converted into a frequency band different from that of the 1st input signal S(CS-IF), and a 1st frequency conversion signal SCS1 subjected to frequency conversion is converted into a frequency band that differs from that of the 1st frequency conversion signal SCS1 and from that of a 2nd input signal S(BS-IF). Thus, the frequency band of the 1st input signal S(CS-IF) and the 2nd input signal S(BS-IF) is converted into a different frequency band and then the two input signals are mixed and the mixed signal is sent through one cable.
