2.4GHz SiGe,
High IP3 Low-Noise Amplifier
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.
Features
o Low Noise Figure (2.0dB at 2450MHz)
o High Gain: 16dB
o Adjustable IP3 and Bias Current
o Low-Power Standby Mode
o On-Chip Output Matching
o +2.7V to +5.5V Single-Supply Operation
o Ultra-Small 6-Pin SC70 Package
