Abstract :
A 60 GHz phased-array transmitter for multi-Gb/s non-line-of-sight links is fully integrated in a 0.12 ¿m SiGe BiCMOS process. It consists of an up-conversion chain with synthesizer, a power distribution tree and 16 phase-shifting front-ends. The IC occupies 44 mm2, draws 1.2 W excluding front-ends, and delivers 9 to 13.5 dBm OP1dB per element drawing 164 to 313 mW per front-end.
