A fully integrated matrix amplifier with two rows and four columns (2-by-4) fabricated in a three-layer metal 0.18-/spl mu/m silicon-on-insulator (SOI) CMOS process is presented. It exhibits an average pass-band gain of 15 dB and a unity-gain bandwidth of 12.5 GHz. The input and output ports are matched to 50 /spl Omega/ using m-derived half sections; the measured S/sub 11/ and S/sub 22/ values exceed -7 and -12 dB, respectively. Integrated in 2.0/spl times/2.9mm/sup 2/, it dissipates 233.4 mW total from 2.4- and 1.8-V power supplies.
