RF2460
PCS CDMA LOW NOISE AMPLIFIER/MIXER
1500MHz TO 2200MHz DOWNCONVERTER
The RF2460 is a receiver front-end designed for the receive section of PCS
CDMA and W-CDMA applications. It is designed to amplify and downcon-
vert RF signals 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 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 for CDMA PCS communica-
tions. 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.
