Development of a spaceborne C-band klystron for the MetOp-SG mission

A compact, conduction-cooled 5.355 GHz Klystron, based on EIK technology, has been developed for use in the Scatterometer Instrument segment of the forthcoming MetOp-Second Generation mission. Two engineering model Klystrons have been built since the start of the development effort in 2016 and a full space-qualification model will follow in 2017. The Klystron draws upon space heritage from higher frequency Extended Interaction Klystrons developed for the CloudSat and EarthCARE programs, and utilizes a new RF circuit design, tailored to the MetOp-SG requirements.
