摘要
随着有源器件不断地被应用在非线性工作区域,器件的非线性特性进行快速和准确的测量显得尤为重要,X参数作为S参数的自然扩展[1],可以被用来表征器件的非线性特征。本文对X参数定义进行阐述,并采用安捷伦的先进设计系统软件ADS提取X参数,最后将X参数用于负载牵引测量,对X参数的特性进行仿真。
As the active devices are constantly used in nonlinear region, the nonlinear characteristics of the device for rapid and accurate measurement appears particularly important, X parameter as a natural extension of S-parameters,which could be used to characterize the nonlinear characteristics of device. In the paper, It defines X parameter and makes use of Agilent＇s advanced Design System software to extract X parameter, at last, it makes X parameter apply to measure of Load pull and simulate characteristics of X parameter.
