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 a
SiGeHBT process and packaged in a 20-pin leadless
chip carrier with an exposed die flag.
