Abstract

Summary form only given. The VKA2400 series of Ka-band EIKs (extended interaction klystrons), for use in satellite communications, are described. They are fixed tuned, wide-bandwidth, permanent magnet focussed amplifiers operating in the 26.5 GHz to 35 GHz range. These flexible devices are capable of producing continuous wave power over 1000 W. Instantaneous bandwidths over 600 MHz are available. The unique multi-gap feature of the EIK significantly increases efficiency compared to a conventional single gap klystron at Ka-band. Electronic efficiencies (excluding collector depression) up to 28% have been achieved. Performance data on the Ka-band EIK is presented, enabling the system engineer to confidently characterize system performance.
