SHF-Klystron Development for Satellite and Ground Station Applications

Development work aimed at klystron design concepts for various satellite and ground station applications in the frequency range 10-15 GHz and output power levels between 500 and 2500 W is described by this paper. Low weight and high efficiency are attractive features for space borne application using periodic focussing and a multistage collector. Test results including FM-transmission data for a single 30 MHz wide TV-channel are given. For application requiring a larger instantaneous bandwidth up to 100 MHz further design concepts have been studied. They include both PPM- and PM-focusing. A large mechanical tuning range of temperature compensated cavities is accomplished using contacting sliding plungers. The paper gives detailed performance data for ground station application.
