Product Description

The RF2461 is a receiver front-end designed for the

receive section of dual-mode CDMA/FM cellular applica-

tions. It is designed to amplify and downconvert RF sig-

nals, while providing 30dB of stepped gain control range.

Features include digital control of LNA gain, mixer gain,

and power down mode. Another feature of the chip is

adjustable IIP3 of the LNA and mixer using an off-chip

current setting resistor. Noise figure, IP3, and other specs

are designed to be compatible with the IS-98B interim

standard for CDMA cellular communications. The IC is

manufactured on an advanced Silicon Germanium HBT

process and is in a 4mmx4mm, 20-pin, leadless chip car-

rier.
