Directional couplers are most commonly made using two coupled transmission lines—placed close enough together so that when energy travels through one, it couples to the other. This method is widely used at microwave frequencies, where transmission line designs are often employed to make many circuit components.
Providing signal samples for measurement or monitoring;
Enabling signal feedback;
Combining transmit and receive signals for antennas;
Achieving antenna beam forming;
Providing taps for cable distribution systems (e.g., cable TV);
Separating transmitted and received signals on telephone lines.
