| 摘 要： | 给出了一种用二端口矢量网络分析仪(VNA)对多端口器件进行测量的方法,该方法运用简单的迭代法,减小由于其余端口所接负载的非匹配性引入的误差,易于通过软件实现。利用该方法对三端口器件巴伦进行测量,并将最后结果与三端口VNA测得的结果进行比较。比较结果表明,幅度误差小于0.2dB,相位误差小于3°。该方法在多端口VNA不可获得的情况下,可以应用到多端口器件的精确测量上。

| Abstract: | A method for multiport device measurement by using a two-port vector network analyzer (VNA) is presented in this paper. This method uses a simple iterative algorithm to reduce the error due to imperfect terminations of the remaining ports. It can be easily implemented in software. A three-port balun transformer was measured using this method and the results were compared to the data measured using a three-port VNA. The compared results show that the error of the amplitude is less than 0.2dB and the error of... |
