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
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.
