Abstract
Detection accuracy is improved with a reduced size. A radio-frequency module includes an antenna terminal, a signal input terminal, a signal output terminal, a mounting substrate, a chip inductor, and a directional coupler. The mounting substrate has a first major surface and a second major surface opposite to each other. The chip inductor is mounted on the first major surface of the mounting substrate. The chip inductor is provided in at least one of a transmitting path between the antenna terminal and the signal input terminal and a receiving path between the antenna terminal and the signal output terminal. The directional coupler is mounted on the second major surface of the mounting substrate, and at least part of the directional coupler is provided in the transmitting path.
