RF2442

RF2442 4 Typical Applications TDMA/CDMA/FM Cellular Rx LNA TDMA/CDMA PCS Rx LNA Low Noise Transmit Driver Amplifier ISM Band LNA/Driver General Purpose Amplification Commercial and Consumer Systems HIGH-LINEARITY LOW NOISE AMPLIFIER Product Description The RF2442 is a low noise amplifier with a very high dynamic range designed for the receive front end of digital cellular applications at 900MHz, 1900MHz, and 2400MHz. It is designed to amplify low level signals with minimum noise contribution while operating in the harsh, interference-rich environments of newly deployed digital subscriber units. The device also functions as an outstanding PA driver amplifier in the transmit chain of digital subscriber units where low transmit noise power is a concern. The device supports trade-offs between linearity and current drain. The designer has control of these trade-offs with the choice of an external bias resistor. The IC is featured in a standard miniature 8-lead plastic MSOP package.
