N2 - This paper presents the design and simulation of a 220-GHz miniaturized slot-antenna-coupled high-temperature superconducting (HTS) mixer, which integrates the HTS junction and the choke filter on one single substrate. The presented mixer utilizes Bi2Sr2CaCu2O8 (BSCCO) intrinsic Josephson junction array as the nonlinear mixing device. To compensate the parasitic capacitance of the BSCCO junction, a short transmission line is used as an inductance for improving impedance matching between the slot antenna and the BSCCO Josephson junction array. The simulation results show that the proposed mixer achieves a conversion gain and noise temperature of -6.74 dB and 266.28 K @ 50K, respectively.
