Abstract
A radio-frequency circuit includes a switch and three filters. The switch is connected to an antenna connecting terminal. One filter has a pass band corresponding to a first sub-band and is configured to connect to the antenna connecting terminal via the switch. The first sub-band is included in a first band used for TDD communication. Another filter has a pass band corresponding to a second sub-band included in the first band and is configured to connect to the antenna connecting terminal via the switch. There is a gap between the first sub-band and the second sub-band. The remaining filter has a pass band corresponding to a third sub-band and is configured to connect to the antenna connecting terminal via the switch. The third sub-band includes the first sub-band, the second sub-band, and the gap.
