摘要
A device for coupling microwave signals with arbitrary phase shifts and power split ratios over broadband may comprise a first branch comprising a cascade of first stripline sections connected to one another. A second branch may comprise a cascade of second stripline sections connected to one another. A single stripline section and a capacitor may be coupled in series to at least one of the branches. The first stripline sections of the first branch and the corresponding second stripline sections of the second branch form broadside coupled stripline sections. Those cascaded coupled stripline sections may be arranged to have a monotonically changing horizontal offsets but at a uniform vertical distance.
