摘要
由于非同轴微波器件接口的特殊性,无法直接与同轴接口的矢量网络分析仪相连进行测试,非同轴器件的微波性能测试面临较大的困难,目前,国内非同轴器件的测试技术已严重滞后其设计开发工作。对非同轴微波器件接口进行了深入研究,设计了针对非同轴微波器件测试的分体式夹具,解决了去嵌入技术问题,并以实例验证了该测试装置的正确性。大量测试表明,该夹具测试传输准确度优于0.2dB。
Non-coaxial microwave devices could not connect directly to the coaxial vector network analyzer due to its special properties;it was difficult to test the performance of non-coaxial microwave devices.Nowadays,the domestic non-coaxial microwave devices test technology lagged far behind its research and development works.The ports of non-coaxial microwave devices were studied,the split-type test fixtures for non-coaxial microwave devices were designed and the problem of de-embedding technique was solved.Finally,the test fixture was fabricated and used to verify the validity.The transfer accuracy of the test fixture is better than 0.2 dB certified by a lot of experiments.
