A 24-GHz 90-nm CMOS beamforming receiver front-end with analog baseband phase rotation

Sammanfattning

A 24 GHz 2-path beamforming receiver front-end
in 90 nm CMOS is presented. It consists of two direct conversion
front-ends followed by a baseband block performing phase
rotation and signal combination. The baseband phase rotation
is performed by combining the quadrature phases using digitally
controlled weights, achieving a phase resolution of 11 degrees.
From each of the two inputs the front-end measures; a conversion
gain of 13 dB, NF < 9 dB, ICP1db = -20.5dBm, IIP3 = -7.5dBm,
LO-RF isolation 48dB, all at a power consumption of 33.6mW
from a 1.2 V supply. The chip area is 1400x850 μm2, including
pads, of which the phase rotation block occupies 400x100 μm2.
