Preliminary
RF9678
5 W-CDMA TRANSMIT MODULATOR AND IF AGC
Typical Applications
• W-CDMA Systems
• EDGE Systems
• CDMA Systems
• TDMA Systems
Product Description
The RF9678 is an integrated complete quadrature modu-
lator and IF AGC amplifier designed for the transmit sec-
tion 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.
