Abstract

In the preferred embodiment, a superconductive microwave delay line is constructed having an epitaxial superconducting conductor (50) and a portion of the ground plane (54) coplanar with the conductor, both formed on the substrate, with the remainder of the ground plane formed by interconnections (56) between the coplanar ground plane (54). Superconducting epitaxial films may be patterned to provide the conductor and coplanar portions of the ground plane. Metal interconnects (56) disposed on the coplanar portions of the ground plane bridge over the conductor (50) and the impedance of the device is adjusted by varying the coverage of the conductor by the interconnects.
