Product Description
The RF2884 is a low noise amplifier with a very high dynamic range designed for a
broad range of applications. This part is ideal for use as a FM LNA in cellular appli-
cations. The device functions as an outstanding front end low noise amplifier, fea-
turing very low noise figure combined with high gain, high IIP3, and low current
consumption. The product is packaged in a Pb-free, 3mmx3mm, QFN plastic pack-
age.
