Product Description
The RF2472 is a general purpose, low-cost, high-perfor-
mance amplifier designed for operation from a 2.7V to 4V
supply with low current consumption. The device is opti-
mized for 2.4GHz LNA applications, but is also useful for
1.9GHz PCS and K-PCS, 900MHz ISM, and 1.5GHz
GPS applications. The RF2472 is available in a very
small industry-standard SOT23 5-lead surface mount
package, enabling compact designs which conserve
board space.
