星载行波管放大器杂波谱抑制的研究
Study of spurious spectrum suppression of spaceborne TWTA
-
摘要: 该文给出了星载行波管放大器(TWTA)杂波谱行为观察的结果,分析了其形成机制,探讨了杂波谱的抑制方法.研究表明只有从TWT设计和EPC电路设计两方面采取措施,才有可能获得高纯频谱。在此基础上,将卫星用TWTA杂波谱振幅降低了10-15dB。Abstract: This paper presents observed results of spurious spectrum of TWTA used for satel-lite. The rnechanism of spurious spectrum formation is analysed and the rnethods of its sup-pression are discussed. It is shown from the study that in order to obtain pure spectrum, the measures rnust be taken for both design of TWT and EPC circuit. Based on this study, the aruplitude of spurious spectrum of spaceborne TWTA has been reduced 10-15dB
