Superconducting Quantum Arrays with High Spurious-Free Dynamic Range

There has been a significant progress in the development of broadband superconductor sensors / amplifiers capable of providing high Spurious-Free Dynamic Range for applications in broadband receiving systems with direct digitization of rf signals. This paper is to review our theoretical and experimental results on Superconducting Quantum Arrays suggested for broadband sensors / amplifiers including active Electrically Small Antennas.
