• Commercial and Consumer Systems
Product Description
The RF2365 is a low noise amplifier with a high dynamic
range designed for the receive front end of digital cellular
applications at PCS/DCS frequencies. It is designed to
amplify low level signals with minimum noise contribution
while operating in the harsh, interference-rich environ-
ments of newly deployed digital subscriber units. The part
provides excellent performance as a LNA for 2.4GHz
radio applications. The IC is featured in a standard
SOT5-lead plastic package.
