RF2442
HIGH-LINEARITY LOW NOISE AMPLIFIER
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 sig-
nals with minimum noise contribution while operating in the harsh, inter-
ference-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 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.
