RF2642
3V 900MHz UPCONVERTER/
DRIVER AMPLIFIER WITH BYPASS MODE
The RF2642 is a complete upconverter and power amplifier 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. Pack-
aged in an industry standard 4mmx4mm, 16-pin, leadless chip carrier,
the device provides a low-cost solution while easing board space limita-
tions.
