A low power 9.75/10.6GHz PLL in SiGe:C BiCMOS for Ku-band satellite LNBs

A low cost / low power PLL for Ku-band satellite down-converters has been fabricated in SiGe:C BiCMOS process. The PLL occupies 0.5mm2 of silicon and draws less than 25mA from 2.7/3.3V supplies. It achieves state-of-art integrated phase noise performance of 1° rms and spurs level below -65dBc.
