An ultra-wideband CMOS LNA for 3.1 to 10.6 GHz wireless receivers

A UWB 3.1 to 10.6 GHz LNA employing an input three-section band-pass Chebyshev filter is reported. Fabricated in a 0.18 /spl mu/m CMOS process, -10 dB over the band, a NF of 4 dB, and an IIP3 of -6.7 dBm while consuming the IC achieves a power gain of 9.3 dB with an input match of 9 mW.
