Aerospace 2.5 GHz Direct Conversion Quadrature Modulator

The AD8346S is a silicon I / Q quadrature modulator, designed to be used from 800MHz to 2.5GHz. 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 AD8346S requires only –10dBm 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 AD8346S has been tested and provides –72dBc ACPR when used in a direct up-conversion CDMA IS95 modulator.

The AD8346S is supplied in 16-lead Bottom Brazed Flat Pack package, and fully specified over –55 to 125 deg C temperature range.

* Output Frequency range 800 MHz to 2.5 GHz
