Zusammenfassung:	A directional coupler includes a main line, a sub-line, an output terminal, a first termination circuit, and a termination switch. The sub-line includes a first end and a second end. The output terminal is connected to one end of the first end and the second end. The first termination circuit connects a first output path, which connects the one end and the output terminal, to a ground. The termination switch switches between connection and non-connection between the first output path and the first termination circuit.
