Directional Couplers: 101

Directional couplers are circuits where each of their four ports is separated from the input port and are passive reciprocal networks. All four of the couplers’ ports should be matched, and the circuit should not experience loss.

There are various types of couplers, including the following:

                ▪              Coupled-line couplers

                ▪              Bethe-hole couplers

                ▪              Multi-hole couplers

                ▪              Bi-directional couplers

                ▪              Dual-directional couplers

                ▪              Hybrid couplers

Directional couplers are used to sample a signal, sometimes both for the reflected and incident waves (an application that is referred to as a reflectometer, which is an essential component of a network analyzer). Directional couplers typically make use of microwave circuit distributed properties. The coupling process typically happens within one—quarter-wavelength or many quarter wavelength components of the device.

Within these distributed couplers, interaction takes place between the energy and fields of each distributed structure, and therefore couples signals from one to the other. Hybrid and …
