Product Description
The RF2369 is a switchable 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. 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 6-lead plastic package.
