ABSTRACT:
A coupled line structure for microwave signals employs a gallium-arsenide substrate having an embedded metallic line located on a surface of the substrate. The surface of the substrate is covered with a thin dielectric layer and at least another metallic line is positioned on the dielectric layer and parallel to the embedded line with a portion of the lines overlapping one another for coupling. A third line can also be disposed on the dielectric layer which line is parallel to the other lines and where the embedded line is connected by a via hole to one of the lines on the dielectric.
