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. This circuit is designed as part of RFMD's newest CDMA chipset, which also includes the RF2667 CDMA/FM Receive IF AGC and Demodulator. The IC is manufactured on an advanced 18GHz FT Silicon Bipolar process, and is supplied in a 48-lead plastic LQFP package.
