A radio-frequency module supports carrier aggregation in which radio-frequency signals in a plurality of frequency ranges are simultaneously transmitted, simultaneously received, or simultaneously transmitted and received. The radio-frequency module includes a plurality of first filters, a plurality of second filters, a switch coupled to an antenna element and the plurality of first filters and configured to control connection and disconnection between the antenna element and each of the plurality of first filters, and a switch coupled to the antenna element and the plurality of second filters and configured to control connection and disconnection between the antenna element and each of the plurality of second filters. No combination of filters selected from both the plurality of first filters and the plurality of second filters are used for carrier aggregation.
