Additional 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.

APPLICATIONS

Cellular/PCS communication systems infrastructure

WCDMA/CDMA2000/PCS/GSM/EDGE

Product Detail

AD8349-EVALZ is 4-layer, FR4-based evaluation board. For normal operation, it requires a 5 V/200 mA power supply which should be connected to the clip leads labeled VPOS and GND. The LO and baseband inputs (which should be biased at 0.4 V) are applied to edge-mounted SMA-type RF connectors (labeled LO, IP, IN, QP,and QN). The AD8349 output is available at the SMA connector labeled VOUT.
