AD8349:  700 MHz TO 2.7 GHz Direct Up-Conversion Quadrature Modulator

Product Details


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.

Recommended PLL's for the AD8349
  • For high performance with integrated VCO, we recommend the ADF4350.
  • For lower cost, power and size with integrated VCO, we recommend the ADF4360-X family of fixed frequency PLL's.
  • For higher performance, higher frequency and faster locktimes, we recommend the discrete Integer-N, ADF4106 or the discrete Fractional-N, ADF4153.
Recommended Differential Dual Baseband TxDAC®'s for the AD8349
  • For generating differential I and Q currents up to 125MSPS, we recommend the AD911X pin compatible family of low power, small size, TxDAC®'s like the AD9117.
  • For even lower power requirements up to 125MSPS, we recommend the pin compatible AD971X family of TxDAC®'s like the AD9717.
  • For higher bandwidths using data rates up to 250MSPS, with low noise and IMD, we recommend the pin compatible AD974X family of CMOS TxDAC®'s like the AD9747 or AD9125 if interpolation is required.
  • For direct conversion transmit applications up to 500 MSPS, we suggest the pin compatible AD978X family of LVDS TxDAC®'s like the AD9783 or AD9122 if interpolation is required.
  • For ultrlow noise and IMD at 1000MSPS, we recommend the AD9122 or the AD9125.
