Design of Waveguide NbN‐Based Superconductor–Insulator–Superconductor Mixer for 650 GHz
Advanced Photonics Research, EarlyView.This research work focuses on a waveguide NbN‐based superconductor–insulator–superconductor mixer operating at 650 GHz. The signal coupling circuit is designed using a waveguide‐microstrip coupling structure, and the return loss obtained is lower than −16 dB. For the mixing circuit, its return loss is less than −7.5 dB, and the return loss reduces with
