Directional Coupler is a passive device that couples part of the broadcast power in a broadcast line, provide the bandwidth, high directivity, and higher power through one is coupled to the other.
Directional Coupler is the devices that sample a minor quantity of Microwave power for measurement purposes. The power capacities include incident power, reflected power, VSWR and values
Directional Coupler is an electric module having four-port circuits with one port being remote from the input port and another being considered as a through the port. The device is normally used to break the input signal and dispersed power. Directional couplers are used in a wide range of applications which involve measurement, power monitoring, and other utilities.
