PROBLEM TO BE SOLVED: To provide a satellite mounted repeater which can improve communication performance.SOLUTION: The satellite mounted repeater has: RF reception sections 3-1 to 3-L which perform a predetermined reception processing to two or more reception signals respectively which are received by satellite mounted reception antennas 1-1 to 1-K; A/D conversion sections 4-1 to 4-L which convert the signal after reception processing is performed into a digital signal; wave dividing sections 5-1 to 5-L which decompose the digital signal into a plurality of narrow-band signals to output them; RF transmission sections 9-1 to 9-M which perform a predetermined transmission processing to transmission signals to be transmitted from satellite mounted transmission antennas 11-1 to 11-N; wave combining sections 7-1 to 7-M which combine the narrow-band signals to input them in the RF transmission sections 9-1 to 9-M; and a switch section 6 which specifies transmission frequencies to input the narrow-band signals into the wave combining sections 7-1 to 7-M so that the two or more reception signals may be transmitted by one transmission beam and frequency bands of the two or more reception signals may not be mutually overlapped. |
