RF2690 datasheet


The RF2690 is an integrated complete IF AGC amplifier and quadrature demodulator designed for the receive section of W-CDMA applications. It is designed to amplify received IF signals, while providing 70dB of gain control range, a total of 90dB gain, and demodulation to base band I and Q signals.This circuit is designed as part of RFMD’s single mode W-CDMA chipset, which includes the RF9678 as modulator and IF AGC and the RF2638 as upconvertor. The IC is manufactured on an advanced 25GHz FTSilicon Bi-CMOS process, and is packaged in a 20-pin, 4mmx4mm, leadless chip carrier.
