RF2679
W-CDMA RECEIVE AGC AND DEMODULAT OR
W-CDMA Systems
The RF2679 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 60dB 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 single-mode W-CDMA Chipset, which also
includes the RF2678 W-CDMA Transmit Modulator and IF
AGC. The IC is manufactured on an advanced 25GHz F
T
Silicon Bi-CMOS process, and is packaged in a
4mmx4mm LPCC-24.
