Product Description
The RF2373 is a low noise amplifier with a very high
dynamic range designed for WLAN and digital cellular
applications. The device functions as an outstanding front
end low noise amplifier or 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 cur-
rent 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.
