  • Patent number: 11750228
    Abstract: There is provided a radio-frequency module that can reduce communication signal loss in both the case of employing one communication band of multiple communication bands and the case of employing two or more communication bands together. A radio-frequency module includes a first switching circuit and matching circuits. The matching circuits are provided individually for a first transmission path, a second transmission path, and a third transmission path. When communications are performed by using only a first communication band, the first switching circuit selects the first transmission path. When communications are performed by using together the first communication band and the second communication band, the first switching circuit selects the second transmission path and the third transmission path.
