PCS CDMA LOW NOISE AMPLIFIER/MIXER

1500MHz TO 2200MHz DOWNCONVERTER

• General Purpose Downconverter

• Commercial and Consumer Systems

• Portable Battery-Powered Equipment

Product Description

The RF2460 is a receiver front-end designed for the

receive section of PCS CDMA and W-CDMA applica-

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

nals while providing 29dB of stepped gain control range

and features digital control of LNA gain, mixer gain, and

power down mode. A further feature of the chip is adjust-

able 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 for CDMA

PCS communications. The IC is manufactured on an

advanced Silicon Germanium Bi-CMOS process and is

assembled in a 20-pin, QFN package with an exposed die

flag.
