SiGe HBT with fmax of 157GHz Based on MBE
基于MBE的fmax为157GHz的SiGe HBT器件

For analog IC applications,not only f T of Si transistor is concerned,but f max of Si transistors is also concerned.In this study,the research for improvement on SiGe HBT f max of 157GHz has been undertaken based on MBE SiGe materials.
