5 to 25 GHz SiGe MMIC oscillators on a commercial process

State-of-the-art monolithic oscillators and VCOs using the commercially available TEMIC SiGe1-process are presented. Results comprise a 4.75 GHz buffered VCO with up to 18 dBm output power and 1 GHz tuning bandwidth, a 17 GHz oscillator with 8 dBm output power and a 25 GHz oscillator delivering 4.2 dBm. For the 25 GHz MMIC-oscillator, a single sideband phase noise of -93 dBc/Hz at 100 kHz frequency offset is achieved. All designs are completely monolithic, i.e., varactor diodes and bias networks are included on chip.
