Abstract :
This paper describes a type of waveguide-to-microstrip transition incorporated with a “built-in” DC/IF return and an offset probe which is proposed for the applications of submillimeter-wave superconductor-insulator-superconductor (SIS) mixers. The effects of the DC/IF return and the probe location and orientation are understood by simulating a 100-GHz transition using the finite element method (FEM). The simulation results are compared to the experimental results of a Ka-band scale model for the simulated transition. The performance of a 100-GHz SIS mixer employing such a transition is finally presented
