Abstract: A radio frequency module includes a module substrate including a first main surface facing a second main surface, and a power amplifier including first and second power amplification devices and an output transformer, which includes a primary coil and a secondary coil, and a capacitor connected to the output transformer. One end of the primary coil is connected to the first amplification device. Another end of the primary coil is connected to the second amplification device. One end of the secondary coil is connected to an output terminal. The output transformer is disposed in or on the module substrate and is disposed closer to one of the first and second main surfaces than the other. The capacitor is disposed in or on the other of the first and second main surfaces and is disposed to overlap the output transformer when the module substrate is viewed in a plan view.
