Typical Applications

鈥?CDMA/FM (AMPS) Systems

鈥?Dual-Mode TACS/JCDMA Systems

鈥?General Purpose Downconverter

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 gain are

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

dard for CDMA cellular communications. The IC is manu-

factured on an advanced Silicon Germanium Bi-CMOS

process and is assembled in a 4mmx4mm, 20-pin, QFN

package.
