摘要

在卫星系统中，星载中继器应始终提供更多的射频功率。特别是在高清晰度电视或互联网等ka波段应用中，必须增加卫星容量以提高数据传输速率。这种容量的增加导致指定射频输出功率的大幅增加。为了满足这一需求，泰雷兹电子器件公司(TED)在法国航天局(CNES)的支持下，通过了传导冷却行波管(TH4816C)的认证，目前正在完成辐射冷却行波管(TH4816R)的认证。这些行波管在Ka频段提供170W的功率。本文给出了TH4816系列设计的主要技术特点及其在17.3 ~ 21.2 GHz全Ka频段内的主要性能。

170W Ka-Band space TWT

In satellite systems, on-board repeaters shall deliver always more RF power. Specifically in Ka-Band applications like HDTV or Internet, the satellite Capacity must be increased to improve the Data Rate Transfer. This Capacity increase leads to a substantial increase of Specified RF Output Power. In order to respond to this demand, Thales Electron Devices (TED), with the support of CNES (French Space Agency), has qualified a conduction cooled TWT (TH4816C) and is currently completing the Qualification of a radiation cooled TWT (TH4816R). These TWTs deliver 170W in Ka frequency band. This paper gives the main technical characteristics of the TH4816 family design and the main performances over the full Ka frequency band from 17.3 to 21.2 GHz.
