1. A radio-frequency module, comprising:
a mounting substrate having a first main surface, a thickness of the mounting substrate along a first direction;
a first power amplifier that is mounted on the first main surface and that amplifies a first transmission signal in a first frequency band, the first power amplifier including a first output terminal through which the first transmission signal is output;
a second power amplifier that is mounted on the first main surface and that amplifies a second transmission signal in a second frequency band different from the first frequency band, the second power amplifier including a second output terminal through which the second transmission signal is output;
a first output matching circuit that is mounted on the first main surface and that receives the first transmission signal amplified by the first power amplifier; and
a second output matching circuit that is mounted on the first main surface and that receives the second transmission signal amplified by the second power amplifier, wherein
the first output matching circuit and the second output matching circuit are mounted along a second direction intersecting with the first direction,
at least one output terminal, among the first output terminal and the second output terminal, is mounted on a output matching circuit side to which the corresponding transmission signal is output,
when the mounting substrate is viewed from a third direction intersecting both the first direction and the second direction, the first power amplifier and the first output matching circuit line up with each other and the second power amplifier and the second output matching circuit line up with each other, and
when the mounting substrate is viewed from the third direction, the first power amplifier and the second power amplifier are between the first output matching circuit and the second output matching circuit.
