The RF2347 is a low noise amplifier with a very high

dynamic range designed for digital cellular applications at

900MHz. 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 miniature 8-lead plastic MSOP

package.
