Processing, Fabrication, and Demonstration of HTS Integrated Microwave Circuits.

Abstract

Work is in progress to determine the dynamic range of superconducting filters by studying their noise and power handling characteristics. The goal is to establish their usefulness in receiver front-end applications. The thermal noise figure of HTS filters and its effect on a filter-low-noise-amplifier chain are being examined. Calculations of the noise figures for the filter alone and for the filter-amplifier chain are shown as a function of filter loss. Notice that, for cooled passive devices, the noise figure is lower than the insertion loss.
