RF2850 Direct Quadrature Modulator
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 1700 MHz to 2500 MHz with excellent carrier and sideband suppression and ultra low noise floor. The device is manufactured on an advanced GaAs HBT process. The RF2850 operates from a single 5 V supply and is packaged in a low cost 4 mm x 4 mm 16-pin leadless package.
