Abstract
In satellite systems, on-board repeaters are required to provide higher and higher levels of RF power. Specifically in Ka band, a substantial increase of RF power is requested in some applications like HDTV and internet to improve the available data rate. In order to respond to this demand, Thales Electron Devices (TED), with the support of CNES (French Space Agency), is developing a TWT (TH4816) which delivers 170W in Ka frequency band. This paper gives the main technical characteristics of the TH4816 design and the main performances over the total Ka frequency band from 17.3 to 21.2 GHz.
