3V LOW NOISE AMPLIFIER/ 3V PA DRIVER AMPLIFIER
Product Description
The RF2878 is a 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 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 SOT 5-lead plastic package. NOTE: The RF2878 is a Pb-free product. If a non-Pb-free product with the same functionality and package is desired, please see the RF2361.
