SWIFT算法在微波测量去嵌入中的应用

在微波网络的S参数测量中往往会遇到夹具效应，要想得到待测件的准确参数，就必须进行去嵌入计算以消除转接头带来的影响。文章提出利用SWIFT优化算法进行辅助去嵌入计算的方法，利用该去嵌入方法所获得的均衡器单子结构网络参数进行计算级联的结果与测量结果一致性很好，表明该方法的有效性和可应用性。另一方面由于该去嵌入方法中接头的参数是基于测试获得的，因此对接头本身加工精度的要求不高，使得本文所提出的S参数去嵌入方法能应用在一般的接头去嵌入上。

Application of SWIFT Algorithm in the Microwave Measurement

The clamp effect can produce error in the microwave measurement. In order to get the ex- act network parameters of apparatus, it is necessary to use the de-embed calculation to avoid the tie- in＇ s influence. The SWIFT optimization algorithm is brought forward to assist the de-embed calcula- tion in this paper. The equalizer single-structure＇ s network parameters can be got by using the de- embed calculation. Two equalizer single-structures＇ interconnecting results can be got by calculation and measurement. By comparing the calculation result with the measurement result, they have a good coherence. The results indicate the de-embed calculation is efficient and applicable. Because the de-embed calculation is based on the measurement, the algorithm hasn＇ t the rigor requirement of machining precision. So the de-embed calculation can be used widely in microwave measurement.
