Abstract :
A fully-integrated LNA is presented in context of a dual-band direct-conversion receiver architecture for 5-6 GHz wireless LAN applications. Designed and fabricated in a 0.24 μm standard digital CMOS process, the LNA exhibits a wideband 50 ohm input matching with S11 of -23.5 dB at 5.5 GHz. The measured IIP3 and P1dB are +10 dBm and -1.5 dBm respectively. It has a noise figure of 4.8 dB at 5.5 GHz. The LNA is shown to meet the requirements of a dual-band receiver architecture for the IEEE 802.11a WLAN standard.
