Bi-directional coupler
A bi-directional coupler includes a first individual directional coupler and a second individual directional coupler, which are individual electronic components having mutually equivalent circuit configurations. Each of the first and second individual directional couplers includes: a first terminal; a second terminal; a third terminal; a fourth terminal; a main line connecting the first terminal and the second terminal; and a subline connecting the third terminal and the fourth terminal. The subline includes first and second coupling line sections configured to be electromagnetically coupled to the main line, and a matching section provided between the first and second coupling line sections. The second terminal of the second individual directional coupler is electrically connected to the second terminal of the first individual directional coupler.
