高达110GHz频段的电路材料测量结果

有许多测试方法可用来评估微波波段的高频材料特性，却很少有测试方法可用来评估毫米波波段的电路材料特性。每种测试方法有它各自的能力和限制。视频将讨论用于毫米波波段的常用测试方法并展示不同高频材料的测试结果数据。当频率升高到110GHz时，测试数据将说明铜表面粗糙度和表面处理工艺对电路的影响。

Description:
There are several test methods that can be used to characterize high frequency materials at microwave frequencies, however there are fewer test methods which can be used to evaluate materials at millimeter-wave frequencies. Each of these test methods has their own set of capabilities and limits. Common test methods which can be used at millimeter-wave frequencies will be discussed and data will be shown with measured results on several different high frequency materials. Some test data shown will illustrate the impact of copper surface roughness as well as final plated finish up to 110 GHz.
