Abstract :
The microwave noise performance of Si/SiGe double-heterojunction bipolar transistors has been evaluated on-wafer, for frequencies ranging from 2 to 26 GHz. Noise figures of 0.6 dB at 2 GHz and 1.2 dB at 10 GHz were found to be among the lowest reported for bipolar transistors in general.
