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.
