RF2352
3V CDMA DRIVER AMPLIFIER
Typical Applications
• TDMA/CDMA/FM Driver Amplifier
• Low Noise Transmit Driver Amplifier
• General Purpose Amplification
• Commercial and Consumer Systems
Product Description
The RF2352 is a low noise driver amplifier for 900MHz
CDMA/AMPS applications. The device is designed for
operation from 2.7V to 3.6V, and features selectable high
and low gain modes. In high gain mode, the device will
provide about 19dB of gain, and the linearity and current
drain are set with an external resistor, allowing the
designer to select the optimum performance for a given
application. In the low gain, or “bypass” mode, the gain is
controlled by an external attenuator network, and the
device draws essentially no current. The part is fabricated
using a high performance silicon BiCMOS process, and is
packaged in a 4mmx4mm, 16-pin, leadless chip carrier.
