Dual Directional Couplers

Similar to our stripline directional couplers, Marki RF/microwave Dual Directional Couplers consist of two back to back stripline directional couplers. They allow a user to measure both forward and backward traveling waves with poorly impedance matched detectors. High directivity allows them to be used for scalar network and return loss/VSWR measurements.
