基于PCB材料的电路TCDk的重要性

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.
