Abstract
This paper presents a 22–24 GHz CMOS 4-element
phased array based on theAll-RF architecture with very low power
consumption and chip area. The measured array performance,
done at the system level at 22–24 GHz, shows an input and output
match of
13 dB, 9–12 dB gain, 7.5–8.0 dB NF, an IIP3 of
9.5
to
12.5 dBm, and a 4-bit phase control with an rms gain and
phase error of
1.2 dB and
6
, respectively (
0.5 dB and
3
at 23.5–24.5 GHz). The chip consumes 76.5 mA from a 1.5 V supply
and is 3 mm
