Uni-Directional Couplers

Uni-Directional Couplers

A 3-Port Uni-Directional Coupler consists of a main line and a coupled line. One end of the coupled line is internally terminated, while the other end serves as a coupled port.

Ideal for sampling and monitoring power in one direction at a given time. It is necessary to physically reverse the orientation of the unit to change from a forward to a reverse power measurement
