摘要：
Si/SiGe power heterojunction bipolar transistors (HBTs) grown by MBE were dynamically characterised in the common-base configuration. At an emitter current density of 1.1x10(5) A/cm2, a maximum frequency of oscillation of 49GHz was observed. At 10GHz a maximum unilateral gain of 14dB is available, and a CW output power of 1.3W/mm for a device with 10 parallel emitter-fingers of 1x10mum2 each was predicted, from CW measurements.
