SSICT's Divider, Splitter & Coupler


Directional couplers are devices used primarily in the field of RF technology. They couple a defined amount of the electromagnetic power in a transmission line to an additional port(s) enabling the incoming signal to be used in other circuits. An essential feature of directional couplers is that they only transmit power received from the input in one direction. Conversely, power entering any of the output port(s) is coupled to an isolated port, but not to the original input port. A directional coupler designed to split power equally, with equal amplitude and the same phase between the two ports is called a two way power divider.
