X 参数

 Keysight X 参数*代表着高频率设计非线性网络参数的一个新类别。 X 参数:

  • X 参数对于大信号和小信号、线性和非线性器件都适用。
  • 表征元器件在所有端口处于大输入功率情况下所生成的谐波的幅度和相对相位。
  • 正确表征阻抗失配和频率混迭特性,从而能够精确仿真级联的非线性 X 参数模块,例如无线设计中的放大器和混频器。
  • 非线性矢量网络分析仪(NVNA)和先进设计系统 2008 均包含这一功能。
  • X 参数模型支持可添加至 SystemVue 2010 环境中。SystemVue 可把 X 参数模型连接至射频系统级分析,以及全面的物理层基带/DSP 仿真
     

NVNA Nonlinear Measurements and ADS Simulation and Design


X 参数能够帮助您应对射频工程的关键挑战,即级联元器件在大信号工作条件下的非线性阻抗差异、谐波混频和非线性反射效应。 X 参数可以解决复杂的级联问题: 如果分别测量一组元器件的 X 参数,您可以计算 X 参数,然后得出由它们组成的任何级联结构的非线性传递函数。 通常在谐波平衡仿真器环境中执行基于 X 参数的计算。
