Integrated frequency synthesiser in SiGe BiCMOS technology for 60 and 24 GHz wireless applications

A fully integrated silicon-based frequency synthesiser for 60 and 24 GHz applications is presented. The relative frequency tuning range is 5%, and the total power dissipation is 135 mW at 2.3 V supply voltage. Phase noise at 48 GHz is lower than -98 dBc/Hz at 1 MHz offset over the whole tuning range, which is 8 dB lower than in all previous silicon-based solutions
