I/Q Base-band Frequency range dc to 70 MHz
Output Power −3 dBm P1 dB
Noise Floor −147 dBm/Hz
Quadrature Phase Accuracy 1 deg rms

Amplitude Balance 0.2 dB
Low Power with Power Down Function
Single 2.7 V to 5.5 V Supply
Pin compatible with AD8345/AD8349

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.

Product Details

AD8346-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 1.2 V) are applied to edge-mounted SMA-type RF connectors (labeled LO, IP, IN, QP, and QN). The AD8346 output is available at the SMA connector labeled VOUT.
