Product Description
The RF2472 is a general purpose, low-cost, high-performance low noise
amplifier (LNA) designed for operation from a 2.7V to 4V supply with low
current consumption. The device is optimized for 2.4GHz LNA applica-
tions, but is also useful for 1.9GHz PCS, K-PCS, 900MHz ISM band,
1.5GHz GPS, and 4.9GHz to 5.9GHz WLAN applications. The RF2472 is
available in an industry-standard SOT23 5-lead surface mount package,
enabling compact designs which conserve printed circuit board space.
