Typical Operating Circuit

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.
