Preliminary 7 Typical Applications • Multimode W-CDMA/GSM/DCS/EDGE • W-CDMA Systems • GSM Systems RF2689 W-CDMA/GSM/DCS RECEIVE AGC AND DEMODULATOR Product Description The RF2689 is an integrated complete IF AGC amplifier and quadrature demodulator designed for the receive section of W-CDMA and GSM/DCS applications. It is designed to amplify received IF signals, while providing 70dB of gain control range, a total of 90dB gain, and demodulate to baseband I and Q signals. This circuit is designed as part of RFMD’s multimode W-CDMA/GSM/ DCS chipset, which also includes the RF2688 W-CDMA/ GSM/DCS transmit modulator and IF AGC/Upconverter. The IC is manufactured on an advanced 25GHz FT Silicon Bi-CMOS process, and is packaged in a 20-pin, 4mmx4mm, leadless chip carrier. 1.00 0.90 0.60 0.
