AD8345 Datasheet PDF

●The AD8345AREZ is a silicon RFIC Quadrature Modulator for use from 140 to 1000MHz. The part provides a very low noise floor and high output power supporting a significant improvement in output dynamic range. The AD8345 needs a low LO drive level and provides a fully specified 50R buffered output. The part provides excellent amplitude and phase balance and sideband suppression specifications to enable higher order/capacity QAM modulated radios. Additionally the AD8345 has been tested and supports the requirements as an IF modulator within CDMA/GSM/W-CDMA cellular infrastructure equipment and as a direct conversion modulator for the 800 to 900MHz cellular bands.
