SiGe based low noise amplifier for WLAN applications

This paper presents broad band low noise amplifier for WLAN applications featuring both low noise, high linearity and low dc power consumption. Low noise figure lower than 2 dB has been obtained with IIP3 of 9 dBm and power gain larger than 20 dB using an original bias technique. Another issue has been investigated concerning LNA having very low power consumption.We have obtained a Pdc of 9 mW with 2.5 dB noise figure 17 dB gain and IIP3 of 6.2 dBm. # 2003 Elsevier B.V.
