Directional Coupler Directivity Measurement. Indicates the power delivered to the uncoupled load (p4) Directional couplers are used to sample a traveling wave on one line and to induce a usually much smaller image of the wave on another. Directional couplers are very useful devices, in particular we can use them for two major goals in measurement lab: Characterize return loss / impedance matching / vswr. Directional couplers are passive devices used for sampling incident and reflected microwave power, conveniently and accurately, with minimal disturbance to the transmission line. Directional couplers are used in many different testing applications where power or frequency needs to be monitored, leveled, alarmed or controlled. For example, vector network analyzers (vnas) use directional couplers to separate and sample the forward and backward waves that travel to and from the dut’s port. This is a measure of the coupler’s ability to separate waves propagating in forward and reverse directions, as observed at the coupled (p3) and isolated (p4) ports.
