Typical Applications
• TDMA/CDMA PCS LNA
• TDMA/CDMA/FM Cellular LNA
• ISM Band LNA/Driver
Product Description
The RF2472 is a general purpose, low-cost, high-perfor-
mance 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 applications, but
is also useful for 1.9GHz PCS, K-PCS, 900MHz ISM
band, 1.5GHz GPS, and 4.9GHz to 5.9GHz WLAN appli-
cations. The RF2472 is available in an industry-standard
SOT23 5-lead surface mount package, enabling compact
designs which conserve printed circuit board space.
