RF2469
W-CDMA AND PCS LOW NOISE
AMPLIFIER/MIXER DOWNCONVERTER
• W-CDMA Handsets
• PCS Handsets
• General Purpose Downconverter
• Commercial and Consumer Systems
• Portable Battery-Powered Equipment
The RF2469 is a receiver front-end designed for the
receive section of W-CDMA and PCS applications. It is
designed to amplify and downconvert RF signals while
providing 23dB of stepped gain control range and fea-
tures digital control of the LNA gain and mixer gain. A fur-
ther feature of the chip is adjustable IIP3 of the LNA and
mixer using an off-chip current setting resistor. Noise Fig-
ure, IP3, and other specs are designed to be compatible
with W-CDMA and PCS communications. The IC is man-
ufactured on an advanced Gallium Arsenide Heterojunc-
tion

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