扩展OSL方法校准微波双口测试夹具

The Extended OSL Method for Calibrating the Tow-Port Microwave Test Fixtures

常规的OSL(open short load)校准方法具有简便易行的特点 ,被广泛应用于单端口测量的测试夹具的校准 .在本文中 ,OSL方法被首次扩展应用于双端口夹具的校准 ,并消除该方法带来的相位不确定问题 .通过实验证明这种方法与SOLT(short open load thru)

The open short load(OSL)method is very simple and widely used for one port test fixture calibration.In this paper,this method is extended to the calibration of two port test fixtures for the first time.The problem of phase uncertainty arising in this application has been solved.The comparison between our results and those obtained with the short open load thru(SOLT)method shows that the method established is accurate enough for practical applications.
