视频简介

TCDk is a property which all circuit materials possess and it is how much the Dk of the material will change, with a change in temperature.  Ignoring this property can cause RF performance variations when a circuit is deployed in an environment where significant temperature changes are common.  The default test method for determining TCDk is typically done as a raw-material test and this video gives an outline of how to perform TCDk testing in circuit form.  The circuit form testing for TCDk is considered a real-world test as opposed to the raw-material test method, which istypically intended for material characterization. 

TCDk是所有电路材料共有的特性,表示材料Dk随温度变化的程度。忽略这一特性会导致电路在温度常变环境下出现射频性能变化。默认的TCDk测定方法是原材料测试。视频中简要介绍了如何在电路中进行TCDk测试。与原材料不同,上述测试被认为是一种在现实条件下进行材料TCDk特性的表征。
