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.
The MAX2644 is a low‑cost, high‑third‑order intercept point (IP3) low‑noise amplifier designed for 2.4 GHz WLAN, ISM and Bluetooth applications. It features a programmable bias that lets designers optimise input IP3 and supply current for specific uses. The device operates from a single supply of +2.7 V to +5.5 V and is offered in an ultra‑small 6‑pin SC70 package.
Typical specifications include a gain of about 16 dB, a noise figure of 2.0 dB at 2450 MHz, and an input IP3 up to +1 dBm. The datasheet provides absolute maximum ratings, DC and AC electrical characteristics, typical scattering parameters, and layout recommendations for optimal performance.
