This paper presents a 64-84-GHz phase-locked loop (PLL) realized in a low-cost 80-GHz HBT technology. The circuit consists of a wide tuning-range voltage-controlled oscillator, a push-push frequency doubler, a divide-by-32 frequency divider, a phase detector and an active loop filter. The measured phase noise at 1-MHz offset is -106 dBc/Hz. The output power is -2.5 dBm at 64 GHz, and it slowly decreases to -8.1 dBm at 84 GHz, with a maximum dc power consumption of 517 mW. To the authors' knowledge, the circuit achieves the widest frequency tuning range and its in-band phase noise is the lowest among the fully integrated V/W-band PLLs reported to date.
