微波测量校准误差参数去嵌入技术输出窗 microwave measurement calibration error parameter de-embedding technology output window

摘要

射频夹具去嵌入技术通过将测量回路等效为网络级联的思想来实现,通常工作频率低于6 GHz。基于误差模型参数修正原理,利用工作在Q波段回旋行波管输出窗的S参数进行验证,证明了该方法在微波测量去嵌入上具有很高的准确度,并给出了射频夹具去嵌入无法直接用于微波测量去嵌入的原因。回避了射频夹具去嵌入用于微波测量去嵌入的谐振问题,详细介绍了误差模型参数修正原理及具体实施方式,对于微波波导测量去嵌入具有一定的借鉴意义。

Abstract

The de-embedding technology is implemented through the idea that views the measurement circuit as an equivalent network cascade in radio frequency. Usually, the working frequency is below 6 GHz. For it can realize the accurate measurement of the device under test(DUT), it has been the focus for many tests. But when it refers to the de-embedding technology in microwave measurement, the present study is not enough. In order to get the actual value of the DUT, based on the principle of error model parameters correction, this article takes the Gyro-TWT output window as an example to verify the principle and finally gets the actual results of the DUT after de-embedding whose working frequency is on Q band. This principle gets rid of the resonance problem, and shows that the de-embedding principle has a high accuracy in microwave measurement. This article introduces the de-embedding principles and concretes the implementation methods,which have important significance on microwave de-embedding.
