HIGH-LINEARITY LOW NOISE AMPLIFIER
• ISM Band LNA/Driver
• General Purpose Amplification
• Commercial and Consumer Systems
Product Description
The RF2442 is a low noise amplifier with a very high
dynamic range designed for the receive front end of digi-
tal 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 out-
standing PA driver amplifier in the transmit chain of digital
subscriber units where low transmit noise power is a con-
cern. 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.
