摘要

在5-6 GHz无线局域网应用的双频直接转换接收机架构背景下，提出了一种完全集成的LNA。LNA采用0.24 /spl mu/m标准数字CMOS工艺设计和制造，在5.5 GHz时具有50欧姆的宽带输入，匹配-23.5 dB的S/sub / 11。测量的IIP/sub 3/和P/sub 1dB/分别为+10 dBm和-1.5 dBm。它在5.5 GHz时的噪声系数为4.8 dB。该LNA满足IEEE 802.11a WLAN标准的双频接收机架构要求。

A 5-6 GHz fully-integrated CMOS LNA for a dual-band WLAN receiver

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 /spl mu/m standard digital CMOS process, the LNA exhibits a wideband 50 ohm input matching with S/sub 11/ of -23.5 dB at 5.5 GHz. The measured IIP/sub 3/ and P/sub 1dB/ 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.
