A switch circuit (3) is provided for at least one of a previous stage of a VHF-band frequency converter (4) and a previous stage of a UHF-band frequency converter (8). Each switch circuit (3) passes a signal when a frequency converter at a subsequent stage of the switch circuit is operating, and does not pass a signal when the frequency converter at the subsequent stage of the switch circuit is not operating.
