Abstract
Assuming transmission signals in different frequency bands are simultaneously transmitted, the isolation lowering is suppressed. A radio frequency module includes a first power amplifier, a second power amplifier, a first switch, a second switch, a third switch, and a mounting substrate. The first switch, the second switch, and the third switch are configured to be capable of simultaneously connecting the first power amplifier and the second power amplifier to an antenna terminal. The first switch is disposed between the second switch and the third switch in plan view of the mounting substrate from a thickness direction. The second switch and the third switch are disposed on the same main surface out of the first main surface and the second main surface of the mounting substrate.
