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.
