High temperature superconducting components for microwave systems

Starting with an overview of the various requirements placed on substrates for superconducting microwave applications, the current state of the art of high temperature superconducting thin films on different substrate types is discussed. Recent results for several superconducting microwave components that could form important building blocks for advanced microwave systems are presented, including performance data on experimental devices such as narrow band-pass and band-stop filters, superconducting circulators and miniature, low-frequency spiral resonators. Some examples of system types that can most likely benefit from high temperature superconductivity are identified.
