本文研究了0.1 ~ 20 GHz混频器型同轴二端口非线性矢量网络分析仪的校准问题，重点研究了绝对校准技术。从8项误差模型出发，提出了两种可供选择的双端口校准方法，并通过实验验证了其结果与传统的“未知通”法相当。新方法不仅放宽了对“直通”线的要求，为标定提供了更多的选择和方便，而且为检验NVNA八项误差模型的合理性和有效性提供了一种方法。
This paper studies on the calibration of a 0.1–20GHz mixer-based two-port coaxial Nonlinear Vector Network Analyzer (NVNA), especially the absolute calibration techniques. And from the 8-term error model, we present two alternative two-port calibrating procedures, whose outcomes are revealed equivalent to those of the traditional “unknown thru” method by experiments. The new methods not only relax the requirements of “thru” line, provide more choices and more convenience for calibration, but also offer a way to examine the rationality and validity of the 8-term error model for NVNA.
