Abstract
A coupler device is disclosed which has an improved structure. The structure includes a substrate and, input ports and output ports disposed over the substrate. A plurality of inductors and capacitors are further included, which are arranged in a predetermined configuration and coupled between the ports. A layer of dielectric material is also disposed between the inductors and substrate which improves performance by reducing the dissipation losses and enhancing the frequency response of the coupler.
