Description

The AD8346 is a silicon I/Q quadrature modulator, designed to be used from 800 MHz to 2.5 GHz. 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 −10 dBm 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 −72 dBc 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.AVAILABILITYSamples part number (AD8346ARU) and an evaluation board, part number (AD8346-EVAL) are availableOTHER MODULATOR/DEMODULATOR PRODUCTSAD8345- 250 MHz - 1 GHz RF/IF Quadrature ModulatorAD8347- 800 MHz - 2.7 GHz RF/IF Quadrature DemodulatorAD8349- 800 MHz - 2.7 GHz Direct Up-Conversion Quadrature Modulator
