Part details & applications

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.

APPLICATIONS

Cellular/PCS communication systems infrastructure
