Abstract:
Oscillators in SiGe SIMMWIC HBT technology have been relized in coplanar and a newly developed microstrip
environment. Coplanar 24 GHz LC oscillators show 8.7 dBm output power and a phase noise of -99 dBc/Hz @ 100kHz offset.
Coplanar 27 GHz VCO's yield 12.5 dBm output power and a tuning range of 1.28GHz. Microstrip 27 GHz VCO's show
5 dBm output power and a phase noise better than -90 dBc/Hz @ 100kHz offset.
