Design of Superconducting Integrated Matching Circuits
Abstract
In this paper, we developed and investigated superconducting integrated circuits designed to match the impedances of a generator represented by a flux-flow oscillator based on a long Josephson junction and a detector based on a superconductor–insulator–superconductor tunnel junction in the subterahertz frequency range. The structures were modeled using the transfer matrix method. Designs were also calculated in the program of numerical three-dimensional modeling. A qualitative agreement was found between the results obtained by two methods. Three samples with different topologies were designed, covering the frequency range of 250–680 GHz at a level of –2 dB.
