The project was designed to cope with three problems concerning the application of superconductors to industrial microwave problems: defining really pertinent devices, producing homogeneous reproducible films, making these devices. The material specifications provide a two order of magnitude improvement to be considered with respect to the values of the metallization used in microwave devices at room temperature. This implies that the design of some usual components needs to be reconsidered: planar resonators can replace metallic cavities with equivalent performances for the design of filter banks and with a considerable gain in weight and volume especially at frequencies below 5 GHz. At the completion of the research, several objects were available: low Rs superconducting film (Rs<0.4 milliohm); C band narrow bandwidth filter (bandwidth = 0.5 to 1%); high Q 3 dimensional resonators (10 GHz ) (Q = 1 300 000); tapped delay line (up to 10 GHz) (delay = 4 nanoseconds).
