Abstract: A radio frequency module includes a module substrate having main surfaces that are opposite to each other, a plurality of external connection terminals that are disposed on the main surface, power amplifier circuits that are disposed on the main surface, a transformer that is connected to the power amplifier circuit and disposed on the main surface, and a transformer that is connected to the power amplifier circuit and disposed on the main surface. The power amplifier circuit is a Doherty-type power amplifier circuit, and the power amplifier circuit is a differential-amplifier-type power amplifier circuit.

Abstract: A radio frequency module includes a module substrate having main surfaces that are opposite to each other, a plurality of external connection terminals that are disposed on the main surface, a power amplifier circuit that is disposed on the main surface and supports a first power class, a power amplifier circuit that is disposed on the main surface and supports a second power class, a transformer that is connected to the power amplifier circuit and disposed on the main surface, and a transformer that is connected to the power amplifier circuit and disposed on the main surface. The second power class is defined by a maximum output power higher than a third power class. The first power class is defined by a maximum output power lower than the second power class or the same maximum output power as the second power class.
