摘要

如果在输入端和输出端都放置平衡器，则平衡4端口设备的差模行为可以通过简单的2端口测量来表征。但是传统的插入损耗技术不能完全去除平衡器的嵌入。因此，我们提出了“负载-穿过”去嵌入技术，该技术利用平衡器的差模特性来充分提取被测设备的完整差模行为。给出了理论分析和毫米波测量验证。

The “load-thru” (LT) de-embedding technique for the measurements of mm-wave balanced 4-port devices

The differential-mode behavior of a balanced 4-port device can be characterized by simple 2-port measurements if baluns are placed at both the input and the output. But the traditional insertion loss technique is not able to fully de-embed the baluns. Therefore, we propose the “load-thru” de-embedding technique which uses the differential-mode characteristics of a balun to fully extract the complete differential-mode behavior of the DUT. Theoretical analysis and mm-wave measurement verifications are provided.
