In exemplary aspects, the directional coupler includes one or more additional coupling circuits that each include an additional coupling line located adjacent to the primary coupling line and that can be selectively activated to change a frequency response of the directional coupler.

The additional coupling circuit includes one or more switch(es) to allow for the selective coupling of its additional coupling line to the coupling and/or isolation ports of the directional coupler to selectively change and control the frequency response of the primary coupling line.
