What is a Directional Coupler? | Directional Coupler Primer The max peak-to-peak difference at a range of frequencies in the coupling coefficient. Viewed 30k times . The schematic of a directional coupler is shown in Figure 6. So when we say a coupler has a coupling value of 3 dB, it means that 50% of the power is coupled to the coupled port of the coupler and the rest of the power is routed to the output port of a coupler. This module includes 20 dB attenuator and directional coupler which is operates with M9377A PXIe network analyzer direct access receiver. This arrangement, however, has the dis advantage that the load must be dis connected each time a measurement of forward power is desired, and for ward power should be measured each time frequency is changed.
