硅微波功率晶体管镇流电阻的设计

Desigh of Ballasting Resistor for Silicon Microwave Power Transistor

从热稳定条件出发，对扩散镇流电阻的设计进行了详细的计算和分析，讨论了在保证器件增益前提下提高器件热稳定性的措施，器件应用显示出了良好的结果，最后提出了一种新的没有热崩现象存在的高可靠器件的设想。

From the thermal stability condition,a thorough analysis is pre-formed for the desigh of diffused emmitter ballasting resistor.Several methods to approve the stability are disscussed and used in the desigh of a microwave power linear transistor with good results,Finally a novel highly reliable tran-sistor without thermal breakdown is proposed in the paper.
