AB  - A monolithic microwave integrated circuit (MMIC) frequency down-converter based on a compact high-T c superconducting (HTS) device is demonstrated. The on-chip integrated HTS down-converter consists of a 7-9 GHz bandpass filter for RF input, a lowpass filter for intermediate frequency output, and a self-pumped Josephson heterodyne mixer. All the above passive and active components are fabricated on a single 10 mm × 20 mm chip of YBa 2Cu 3O 7-x film on MgO substrate. Characterization of this MMIC HTS down-converter in terms of frequency response, conversion gain, frequency-tuneability, bias dependence, dynamic range, linearity, and intrinsic noise are presented in this paper. © 2012 Crown.
