Abstract :
The design of a millimeter-wave dual-band phase-locked frequency synthesizer in a 0.18 mum SiGe BiCMOS technology is presented. All circuits except the voltage controlled oscillators (VCOs) are shared between the two bands. A W-band divide-by-3 frequency divider is used inside the loop after the VCOs to simplify division-ratio reconfiguration. The 0.9 mm2 synthesizer chip exhibits a locking range of 23.8-26.95/75.67-78. 5 GHz with a low power consumption of 50-75 mW from a 2.5 V supply. The closed-loop phase noise at 1 MHz offset from the carrier is less than -100 dBc/Hz in both bands. The proposed frequency synthesizer is suitable for integration in direct-conversion transceivers for K/W-band automotive radars and heterodyne receivers for 94 GHz imaging applications.
