摘要提出了一种利用矢量网络分析仪单端口校准误差项提取互易二端口网络S参数的方法。该方法要求在不同的参考平面上分别进行两次单端口校准,然后利用两次单端口校准的误差项求解二端口网络的S参数,通过实验验证该方法的正确性。该方法可应用于负载牵引和噪声参数测量过程中阻抗调配网络的S参数提取。

Abstract：A method to extract the S-parameters of the reciprocal two-port network by using the one-port calibration error term of the vector network analyzer is proposed. The method requires two one-port calibrations on difference planes, and then extract the S-parameter of two-port network by using vector network analyzer one-port calibration error term, the accuracy of the proposed method is verified by experiments. The method can be applied to S-parameter extraction of impedance deployment network during load pull and noise parameter measurement.

Key words： metrology S-parameter one-port calibration error model reciprocal two-port network
