New Travelling Wave Tubes for L-Band and S-Band in Orbit Applications

Abstract

The ongoing development in satellite application requires more and more high power travelling wave tubes (TWT) to relieve the requirements for end user terminals and to improve the quality and channel capacity of the satellite down link. Also more types of TWTs are demanded by the customers to obtain a higher flexibility in satellite design with respect to output power, weight and thermal requirements. Thales Electron Devices (TED) therefore has filled up its portfolio of different TWTs for L-Band and S-Band. This paper will present some technical details and illustrate the performance of state- of-the-art tubes.
