A 2.17 dB NF, 5 GHz band monolithic CMOS LNA with 10 mW DC power consumption

The state-of-the-art noise figures of 2.17 dB and 3.0 dB at 5 GHz band from monolithic CMOS LNA's with 10 mW dissipation on thin (/spl sim/ 20 /spl mu/m) and normal (750 /spl mu/m) substrates are presented. Excellent Input return loss (S/sub 11/) of -45 dB, high P/sub 1dB/ of -8.3 dBm and large IIP3 of 0.3 dBm were also obtained. The excellent performance of the LNA's is attributed to the methodology we developed.
