The MAX2649 high-linearity, silicon-germanium (SiGe) low-noise amplifier (LNA) is designed for 5GHz wireless LAN systems based on IEEE802.11a and HiperLAN2 standards. The MAX2649 achieves a 2.1dB noise figure, 17dB gain, and 0dBm IIP3, making it ideal as a firststage LNA in 5GHz OFDM WLAN radio systems.
