General Description
The MAX2644 low-cost, high third-order intercept point
(IP3) low-noise amplifier (LNA) is designed for applica-
tions in 2.4GHz WLAN, ISM, and Bluetooth radio sys-
tems. It features a programmable bias, allowing the
input IP3 and supply current to be optimized for specif-
ic applications. The LNA provides up to +1dBm input
IP3 while maintaining a low noise figure of 2.0dB and a
typical gain of 16dB.
The MAX2644 is designed on a low-noise, advanced
silicon-germanium (SiGe) technology. It operates with a
+2.7V to +5.5V single supply and is available in an
ultra-small 6-pin SC70 package.
