The AD8349 is high performance quadrature modulator design for use as a single stage up-converter within wireless infrastructure equipment.The AD8349 provides a high output power and very low noise floor supporting a significant improvement in the output signal range. Additionally the excellent phase and amplitude balance accuracy support a higher sideband suppression specification enabling higher order / capacity QAM modulated radios.The AD8349 has been tested for use over the common Cellular bands (900 MHz, 1.9 GHz, 2.1 GHz) meeting the needs as specified by the CDMA/GSM Edge/W-CDMA standards.The AD8349 is supplied in 16-lead Thin Shrunk Small Outline (TSSOP) package, and fully specified over -40ºC to 85ºC temperature range.APPLICATIONSCellular/PCS communication systems infrastructureWCDMA/CDMA2000/PCS/GSM/EDGEWireless LAN/wireless local loopLMDS/broadband wireless access systemsAVAILABILITYSamples (part number AD8349ARE) and an evaluation board (part number AD8349-EVAL) are available.
