The RF2667 is an integrated complete IF AGC amplifier and quadrature demodulator developed for the receive section of dual-mode CDMA/FM cellular and PCS applications and for GSM/DCS and TDMA systems. It is designed to amplify received IF signals, while providing 100dB of gain control range, and demodulate to baseband I and Q signals. Noise figure, IP3, and other specifications are designed to be compatible with the IS-98, and J-STD-018 Interim Standard for CDMA cellular communications. This circuit is part of the RFMD line of complete solutions for digital radio applications. The IC is manufactured on an advanced 15GHz FT Silicon Bipolar process, and is packaged in a standard miniature 24-lead plastic QSOP package.
