RF2690 datasheet

Description :

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.

Features

1. Digitally Controlled Power Down Mode
2. 2.7V to 3.3V Operation
3. Digital LO Quadrature Divide-by-4
4. IF AGC Amp with 70dB Gain Control
5. 80dB Maximum Voltage Gain
