Zusammenfassung:	A directional coupler includes a main line, a first sub-line, a second sub-line, a first phase shift circuit, a first short-circuit path, and a first short-circuit switch. The first phase shift circuit is connected between the first sub-line and the second sub-line. The first short-circuit path short-circuits both ends of the first phase shift circuit. The first short-circuit switch switches between conduction and non-conduction of the first short-circuit path.
