Directional couplers are extremely useful passive RF components capable of extracting a small portion of the energy from the main transmission path, and redirecting it to one, or more, coupled ports. As isolation from the coupled ports to the main transmission path is desirable, directional couplers typically have high isolation among the ports. There are ..

Directional couplers are four port passive devices that employ an input port, output port, a port for the coupled signal and a port that is terminated internally. Directional couplers are used to couple a specific proportion of the power traveling in one transmission line out through another connection or port. Directional couplers are used in ..
