Description

This is W-CDMA RECEIVE AGC AND DEMODULATOR. Preliminary RF2690 W-CDMA RECEIVE AGC AND DEMODULATOR 7 Typical Applications W-CDMA Systems Product 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 baseband 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 25GH- FT Silicon Bi-CMOS process, and is packaged in a 20-pin, 4mmx4mm, leadless chip carrier. 1.00 0.90 0.60 0.24 typ 4.00 sq. 0.65 0.30 4 PLCS 3 0.20 2.10 sq. 12° MAX 0.05 Dimensions in mm. 0.75 0.50 0.50 Note orientation of package. 0.23 0.13 4 PLCS 7 QUADRATURE DEMODULATORS NOTES: 1 Shaded lead is Pin 1. 2 Pin 1 identifier must exist on top surface of package by identification mar.
