摘要
介绍了针对影响微波脉冲功率器件可靠性的热性能问题,应用红外热分析技术,对比探测微波脉冲功率器件在动态和直流状态下的温度分布、峰值结温、热阻及其变化规律。
The research of testing technique on dynamic thermal distributing and characteristics of microwave pulse power transistor was introduced. The behaviors of dynamic temperature distributions, maximum junction temperature and thermal resistance under dynamic and DC bias was investigated using infrared microscopy.
