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. RF2689 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 RF2689 is manufactured on an advanced 25GHz FT Silicon Bi-CMOS process, and is packaged in a 20-pin, 4mmx4mm, leadless chip carrier.
