Space-borne EIK technology

Rapid development of advanced millimeter wave radars affected all markets including space-borne Earth observation. Space missions require long-life, high power amplifiers in a compact package with high efficiency and reliability. The Extended Interaction Klystron technology has demonstrated its capability to meet or exceed all requirements for space-borne applications. This paper reviews EIK performance and the specifics of the development, qualification, fabrication and acceptance process. Brief description of current and future missions is presented.
