行波管与速调管的离子噪声分析

Analysis of Ion Noise in TWTs and Klystrons

  • 摘要: 从波动理论与运动学理论出发,采用小信号近似,分析了行波管与速调管中的离子噪声现象,推导出基于离子张驰振荡引起的相位噪声表达式,并对离子噪声形成的相位噪声特性进行分析,指出随着电位波动的幅度增大,相位噪声同时增加;载波信号频率越高,相位噪声越高。

     

    Abstract: Ion noise of TWTs and klystrons are analyzed using small signal method by motion theory and moment theory. The relationship between phase noise and signal frequency, voltage fluctuation are obtained. From the analysis results we find when the amplitude of voltage fluctuation and signal frequency increase, the phase noise would increase.
