A 3‐GHz‐bandwidth real‐time spectral‐analysis receiver has been demonstrated. The fully integrated compressive receiver is based on the chirp‐transform algorithm and uses a high‐ T c superconductive (HTS) tapped‐delay‐line chirp filter with a time‐bandwidth product of 40. The 3‐GHz bandwidth of the HTS chirp filter is unobtainable using other technologies such as surface acoustic waves. This prototype receiver, a combination of an HTS passive microwave component and conventional semiconductor circuits, demonstrates a microwave system that could not be built without the unique HTS component. © 1993 John Wiley & Sons, Inc.
