AD8346:  2.5 GHz Direct Conversion Quadrature Modulator

Product Description

The AD8346 is a silicon I / Q quadrature modulator, designed to be used from 800MHz to 2.5GHz. The part is optimized for lower power applications, yet provides a very low noise floor and high output power for the given supply current.

The AD8346 requires only –10dBm LO drive level and provides a fully specified 50 ohm buffered output.

The part provides excellent amplitude and phase balance and sideband suppression specifications to enable higher order / capacity QAM modulated radios.

Additionally the AD8346 has been tested and provides –72dBc ACPR when used in a direct up-conversion CDMA IS95 modulator.

The AD8346 is supplied in 16-lead Thin Shrunk Small Outline (TSSOP) package, and fully specified over –40 to 85 degC temperature range.
