Development of superconductive parallel junction arrays for Submm-wave local oscillator applications

In order to develop Submillimiter-wave fully Integrated Superconducting Receivers (SIRs) based on parallel small SIS junction arrays (multijunction) operating as local oscillator, we investigate their performance through measurement and simulation. Multijunction may be an interesting alternative to LJJ because it allows wide LO tunability, wide impedance matching bandwidths and increase design flexibility and control of technological parameters.
