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.

Abstract: A directional coupler includes a main line, sub lines, and a multilayer substrate. The multilayer substrate includes dielectric layers. The multilayer substrate has a first and a second principal surface. The main line, the first, second, and third sub lines are each formed in a looped shape in plan view from a thickness direction of the multilayer substrate, and are provided to different dielectric layers among the dielectric layers. The first, second, and third sub lines have first distances different from each other. Among the first, second sub line, and third sub lines, the longest sub line having the longest first distance and the shortest sub line having the shortest first distance are disposed on the first principal surface of the main line, and the intermediate sub line having the intermediate first distance is disposed on the second principal surface of the main line.
