RF2642
3V 900MHZ UPCONVERTER/
DRIVER AMPLIFIER WITH BYPASS MODE
• CDMA/AMPS Cellular Systems
• TDMA/AMPS Cellular Systems
• General Purpose Upconverter/Driver
• Portable Battery-Powered Equipment
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.
• Single Supply 3.0V Operation
• Step Gain Control
• Power Down Control
• ACPR1=61dBc@885kHz with
POUT=+5dBm
• Small Leadless LCC 16-Pin Package
