Preliminary RF9678 W-CDMA TRANSMIT MODULATOR AND IF AGC 5 Typical Applications • W-CDMA Systems • EDGE Systems • CDMA Systems • TDMA Systems Product Description The RF9678 is an integrated complete quadrature modulator and IF AGC amplifier designed for the transmit section of W-CDMA applications. It is designed to modulate baseband I and Q signals, and amplify the resulting IF signals while providing 55dB of gain control range. This circuit is designed as part of RFMD’s single mode W-CDMA Chipset, which also includes the RF2679 W-CDMA Receive IF AGC and Demodulator. The IC is manufactured on an advanced Silicon Bi-CMOS process, and is supplied in a16-pin leadless chip carrier. .80 .65 1.00 0.85 .60 .24 typ 4.00 sq. .65 .30 4 PLCS 5 MODULATORS AND UPCONVERTERS .35 2 .23 [ ... ]
