The MAX2648 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 LNA provides high gain, low noise, and high linearity performance, allowing it to be used as a first-stage LNA, an LO buffer, or a transmitter driver amplifier. This highly versatile amplifier provides 17dB gain, 1.8dB noise figure, and 0dBm input third-order intercept point (IIP3) while consuming only 12mA.
