A radio frequency module includes: a module board that includes a first principal surface and a second principal surface on opposite sides of the module board; a first power amplifier configured to amplify a transmission signal in a first frequency band; a second power amplifier configured to amplify a transmission signal in a second frequency band different from the first frequency band; and a switch having a first pole connected to an input terminal of the first power amplifier and a second pole connected to an input terminal of the second power amplifier. The first power amplifier and the second power amplifier are disposed on the first principal surface, and the switch is disposed on the second principal surface.
