Dual Directional Couplers

Dual Directional Couplers

A 4-Port Dual Directional Coupler employs two, 3-Port Uni-Directional Couplers internally connected, in tandem, providing measurement of both forward and reverse power.

Ideal for simultaneously monitoring a system’s forward and reverse power and for reflectometer measurements. Unlike the Bi-Directional Coupler, the directivity of the Dual Directional Coupler is unaffected by the loads on the coupled ports.
