MAX2644

19-1786; Rev 1; 11/03 KIT ATION EVALU E L B A AVAIL 2.4GHz SiGe, High IP3 Low-Noise Amplifier General Description 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 MAX2644 The MAX2644 low-cost, high third-order intercept point (IP3) low-noise amplifier (LNA) is designed for applications in 2.4GHz WLAN, ISM, and Bluetooth radio systems. It features a programmable bias, allowing the input IP3 and supply current to be optimized for specific 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. ________________________Applications Bluetooth 802.11 WLAN Home RF Satellite CD Radio 2.4GHz ISM Band Radios 2.4GHz Cordless Phones Wireless Local Loop (WLL) MAX2644EXT-T PART Ordering Information TEMP RANGE -40°C to +85°C PINPACKAGE 6 SC70 TOP MARK AAG Typical Operating Circuit RBIAS 1.2kΩ VCC BIAS BIAS VCC Pin Configuration TOP VIEW C1 33pF RF INPUT L1 3.3nH RFIN RFOUT RF OUTPUT BIAS 1 6 RFOUT GND 2 MAX2644 5 GND RFIN 3 4 VCC MAX2644 GND SC70-6 ________________________________________________________________ Maxim Integrated Products 1 ...
