Low phase noise 2 GHz HBT push-push VCO based on an advanced low frequency noise model

After investigation of the possible HBT low frequency noise sources and their localization in order to extract a HBT low frequency noise model, the realisation and performance of an S band voltage controlled oscillator (VCO) is reported. This VCO is fully integrated in MMIC technology, and is based...

Beschreibung
Zusammenfassung:	After investigation of the possible HBT low frequency noise sources and their localization in order to extract a HBT low frequency noise model, the realisation and performance of an S band voltage controlled oscillator (VCO) is reported. This VCO is fully integrated in MMIC technology, and is based on a push-push topology. The circuit is covering 340 MHz tuning range around a centre frequency of 2 GHz with a phase noise of -95 dBc/Hz at 10 KHz offset.
