RF2850

RoHS Compliant & Pb-Free Product

Typical Applications

鈥?UMTS Base Stations

鈥?CDMA Base Stations

鈥?GSM-EDGE/EGSM Base Stations

Product Description

The RF2850 is a direct quadrature modulator for use in

base stations and other communications systems.

RF2850 supports PCS, GSM, EDGE, CDMA2000, and

UMTS standards. This device features a narrow-band

operation at 1700MHz to 2500MHz with excellent carrier

and sideband suppression and ultra low noise floor. The

device is manufactured on an advanced GaAs HBT pro-

cess. The RF2850 operates from a single 5V supply and

is packaged in a low cost 4mmx4mm 16-pin leadless

package.
