3V LOW NOISE AMPLIFIER/
3V PA DRIVER AMPLIFIER
• TDMA/CDMA/FM Cellular PCS LNA
• Low Noise Transmit Driver Amplifier
• General Purpose Amplification
• Commercial and Consumer Systems
The RF2878 is a low noise amplifier with a very high
dynamic range designed for digital cellular applications.
The device functions as an outstanding front end low
noise amplifier or power amplifier driver amplifier in the
transmit chain of digital subscriber units where low trans-
mit noise power is a concern. When used as an LNA, the
bias current can be set externally. When used as a PA
driver, the IC can operate directly from a single cell Li-ion
battery and includes a power down feature that can be
used to completely turn off the device. The IC is featured
in a standard SOT 5-lead plastic package.
NOTE: The RF2878 is a Pb-free product. If a non-Pb-free
product with the same functionality and package is
desired, please see the RF2361.
