Preliminary RF2668 CDMA/FM TRANSMIT MODULATOR, IF AGC, AND UPCONVERTER WITH INTEGRATED PLL 5 Typical Applications • CDMA/FM Cellular and PCS Systems • Tri-Mode/Dual-Band CDMA Applications • W-CDMA Systems • Wireless Local Loop Systems • Spread-Spectrum Cordless Phones • High Speed Data Modems Product Description The RF2668 is an integrated complete quadrature modulator, IF AGC amplifier, upconverter, and PLL, designed for the transmit section of dual-mode CDMA/FM cellular, PCS, and tri-mode CDMA applications. It is designed to modulate baseband I and Q signals, amplify the resulting IF signals while providing 95dB of gain control range, and perform the final upconversion to UHF. Noise Figure, IP3, and other specifications are designed to be compatible with the IS-98 Interim Standard.
