Space qualified low-/high-power radar TWTs

This paper is a report about recent development activities in the area of space-qualified pulsed traveling wave tubes (TWTs). For an economical development in such a low-volume market, the application of a modular design concept is necessary. As an example for such a concept, two projects will be described, a high-power X-band TWT with 6-kW peak output power and a low-power Ku-band TWT with 135-W peak output power.
