Abstract :
This paper presents the design and the fabrication of a compact MIC 10 GHz single-transistor oscillator. It includes a packaged SiGe HBT (Infineon BFP740F) along with a low-Q coupled line resonator and only consumes 5 mA from a 3V power supply for an output power of -6 dBm. Its phase-noise has been measured at -117 dBc/Hz @100 kHz offset. Such performance is the result of a careful modeling process. The two most challenging aspects of the design were the stability analysis of the 10 GHz oscillator in hybrid technology and phase-noise optimization.
