se Transmit Driver Amplifier • General Purpose Amplification • Commercial and Consumer Systems     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 use
