RF2361
3V LOW NOISE AMPLIFIER/
3V PA DRIVER AMPLIFIER
The RF2361 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 transmit 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 RF2361 is a non-Pb-free product. If a Pb-free product with the same
functionality and package is desired, please see the RF2878.
