Abstract
A directional coupler includes a main line, a first sub-line, a second sub-line, a termination circuit, a selector switch, and a short-circuiting switch. The termination circuit terminates at least one of the first sub-line and the second sub-line. The selector switch connects the first sub-line and the termination circuit in a first mode and connects the second sub-line and the termination circuit in a second mode. The short-circuiting switch short-circuits both ends (a first end and a second end) of the second sub-line in the first mode.
