This paper demonstrates a dual-band LO generation system using a low phase noise single-band 40GHz VCO as the signal source. The LO generation system has two outputs: single-band LO1 at 20GHz and dual-band LO2 switchable between 10GHz and 15GHz. Implemented in 0.25-µm SiGe:C BiCMOS, the VCO achieves a phase noise of -106.8dBc/Hz at 1-MHz offset from 40GHz with a frequency tuning range of 9.7%.
