本文在俞忠钰、王士林两同志的指导和帮助下,对高频大功率晶体管的温度分布进行了较严格的数学分析。得到了用于大功率情况下的晶体管的温度分布公式。从而确定了热沉对硅片表面温度分布的影响。所得到的温度分布公式为高频大功率晶体管的热学设计提供了参考。
Under the guidance and help of two comrades Yu Zhongyu and Wang Shilin, this paper has carried out a rigorous mathematical analysis on the temperature distribution of high-frequency high-power transistors. The temperature distribution equation of the transistor for high power is obtained. Thus, the effect of heat sink on the temperature distribution on the surface of silicon wafer was determined. The obtained temperature distribution formula provides a reference for the thermal design of high frequency high power transistor.
