Abstract: This work is aimed at the development, research and optimization of superconducting integrated circuits designed to match the impedances of a long Josephson junction generator, the so-called flux generator (FFO) and a superconductor-insulator-superconductor (SIS) detector in the sub-terahertz frequency range. Numerical calculations of integrated circuits designed to optimize the parameters of transmission lines are presented. The main parameters of the lines and their influence on signal propagation are determined. The results of optimization of integrated matching circuits in the range of 450–700 GHz are demonstrated.

Keywords: integrated matching circuits, Josephson junctions, sub-terahertz generator.
