The Irish company Farran Technology supplies ESA with high-frequency microwave components and subsystems. Since 1998, the improved materials used for integrated circuits have permitted the production of integrated circuit devices able to operate within the millimetre-wave spectrum - the 30-300 GHz range of the frequency spectrum - used for a broad range of applications from advanced astronomy to broadband radio communications. This technology has now been used to build the improved security scanner Tadar.
