Coplanar and microstrip oscillators in SiGe SIMMWIC technology

Oscillators in SiGe SIMMWIC HBT technology have been realized 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 @ 100 kHz offset. Coplanar 27 GHz VCO's yield 12.5 dBm output power and a tuning range of 1.28 GHz. Microstrip 27 GHz VCO's show 5 dBm output power and a phase noise better than -90 dBc/Hz @ 100 kHz offset.
