RF2196
0 3V PCS LINEAR POWER AMPLIFIER
RoHS Compliant & Pb-Free Product
Typical Applications
• 3V CDMA PCS Handsets
• 3V CDMA 2000 PCS Handsets
• 3V CDMA KPCS Handsets
• 3V TDMA/GAIT PCS Handsets
• Spread-Spectrum Systems
• Portable Battery-Powered Equipment
Product Description
The RF2196 is a high-power, high-efficiency linear ampli-
fier IC targeting 3V handheld systems. The device is
manufactured on an advanced Gallium Arsenide process,
and has been designed for use as the final RF amplifier in
3V CDMA and CDMA2000 handsets as well as other
applications in the 1750MHz to 1910MHz band. The
RF2196 has a low power mode to extend battery life
under low output power conditions. The package is an
ultra small 4mmx4mm, 16-pin QFN plastic package with
backside ground.
