摘要
如何实现非同轴微波器件S参数的精确测量一直是业界的技术难题,制作、使用微波夹具是实现其网络参数直接测量的主要途径之一。文章介绍了传统夹具测试方法,重点论述了运用TRL校准技术进行夹具测量的解决方案,并给出夹具TRL校准件设计方法和注意事项。通过具体夹具校准件的设计和测量试验完成了设计验证,该技术方案能够很好地去除夹具误差、显著提高测试精度,并具有较强的可操作性。
How to realize the accurate measurement of S-parameters of microwave devices has been the difficult technical problem of the industry,with one of main methods being making and using fixtures.This article introduces traditional kinds of fixture techniques,and then discusses the solution of fixture with TRL calibration,giving the designing method and matters needing attention of TRL cal-kits.A series of TRL cal-kits are produced and an experimental is designed,to prove that the method can calibrate the measurement error and improve the testing accuracy effectively.
