DEMONSTRATION OF A 3-GHZ-BANDWIDTH REAL-TIME SPECTRAL-ANALYSIS RECEIVER BASED ON A HIGH-T(C) SUPERCONDUCTIVE CHIRP FILTER

A 3-GHz-bandwidth real-time spectral-analysis receiver has been demons trated. The fully integrated compressive receiver is based on the chir p-transform algorithm and uses a high-T(c) superconductive (HTS) tappe d-delay-line chirp filter with a time-bandwidth product of 40. The 3-G Hz bandwidth of the HTS chirp filter is unobtainable using other techn ologies such as surface acoustic waves. This prototype receiver, a com bination of an HTS passive microwave component and conventional semico nductor circuits, demonstrates a microwave system that could not be bu ilt without the unique HTS component.
