| Abstract(in English) | An inhomogeneous distributed junction array, which consists of different areas of junctions and lengths between every two junctions distributed on superconducting stripline, has been proposed and the performances of mixing have been theoretically investigated using the equivalent circuit model and Tucker's theory. A set of areas of junctions and lengths between every two junctions has been determined so as to minimize a reflection coefficient of an S-parameter, S_<11>, at the input port in the array. In the result, it is demonstrated that the degradation of mixer performances, which is always observed at certain frequencies in the conventional array with same area and length of junctions, can be considerably improved in the inhomogeneous array. This demonstration indicates that the inhomogeneous distributed junction arrays can be considered to be greatly promising for its extension to the submillimeter and THz wavelengths, at which the large critical current density is needed for SIS mixers. |
