Abstract:
A radio-frequency module includes switch elements, first signal paths, band pass filters, first matching circuits, second signal paths, and second matching circuits. Each of the first signal paths is connected between one end of a corresponding one of the switch elements and an antenna terminal. Each of the band pass filters is connected to a corresponding one of the first signal paths and allows a radio-frequency signal of one of the plurality of frequency bands to pass therethrough. Each of the first matching circuits is connected to a corresponding one of the first signal paths. Each of the second signal paths is connected to a corresponding one of the switch elements. Each of the second matching circuits is connected to a corresponding one of the second signal paths. A component included in the first matching circuits and a component included in the second matching circuits are electromagnetically coupled.
