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.
The MAX2648 is designed on a low-noise, advanced SiGe process optimized for high-frequency applications. It operates over a +2.7V to +3.6V supply range. The device is packaged in a tiny 2x3 chipscale package (UCSP™) with six solder bumps, measuring 1.0mm x 1.5mm.
