3V 900MHz UPCONVERTER/

DRIVER AMPLIFIER WITH BYPASS MODE

RoHS Compliant & Pb-Free Product

Typical Applications

• CDMA/AMPS Cellular Systems

• TDMA/AMPS Cellular Systems

• General Purpose Upconverter/Driver

• Portable Battery-Powered Equipment

Product Description

The RF2642 is a complete upconverter and power ampli-

fier driver designed for CDMA applications. The design

features driver amplifier high and low gain states. In the

low gain state, the gain is adjustable and the device

draws less current. The upconverter is always on. The

power down mode turns off the driver amplifier. The

device features balanced IF inputs, single-ended LO input

and RF output for ease of interface. Packaged in an

industry standard 4mmx4mm, 16-pin, leadless chip car-

rier, the device provides a low-cost solution while easing

board space limitations.
