    The MAX2649 high-linearity, silicon-germanium (SiGe) low-noise amplifier (LNA) is designed for 5GHz wireless LAN systems based on IEEE® 802.11a and HiperLAN2 standards. The MAX2649 achieves a 2.1dB noise figure, 17dB gain, and 0dBm IIP3, making it ideal as a first-stage LNA in 5GHz OFDM WLAN radio systems.

    This device operates over a +2.7V to +3.6V supply range and features low overall current consumption (12.5mA). The MAX2649 also includes a shutdown mode to save power when the receiver is inactive.

    The LNA is designed on a low-noise, advanced SiGe process optimized for high-frequency applications. The device is available in a tiny 2 x 3 chip-scale package (UCSP™) (1mm x 1.5mm).
