摘要
本文首先讨论了矢量网路分析仪TRL校准技术对校准件的要求,并根据校准原理设计出了脊波导TRL校准件的尺寸。由于脊波导脊的重合性对校准件与测试端面连接处的反射具有较大影响,对校准件采用精确定位和表面抗氧化处理。最后利用网络分析仪的10项误差修正原理完成了脊波导的TRL校准,实现了脊波导器件微波参数的准确测试。
The design requirement of TRL calibration kit is discussed in this paper. The dimensions of the calibration kit for double ridge waveguide were designed according to calibration theory. Accurate alignment and surface anti-oxidation processing were applied to the calibration kit to reduce the influence of ridge mismatch. The TRL calibration was completed using 10 error correction models in the vector network analyzer. The accurate measurement of double ridge waveguide device was realized.
