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.

Abstract: A radio-frequency module includes a mounting substrate and first and second power amplifiers. The first and second power amplifiers are each mounted on one main surface of the mounting substrate. The first power amplifier includes a first input terminal and a first outer periphery. The first outer periphery includes a first edge section. The second power amplifier includes a second input terminal and a second outer periphery. The second outer periphery includes a second edge section. The second edge section opposes the first edge section in a first direction. The first input terminal is disposed in the first edge section of the first power amplifier. The second input terminal is disposed in the second edge section of the second power amplifier. The first and second input terminals do not overlap each other in the first direction.
