The very wide IF bandwidth of more than 1GHz makes the LTC5586 particularly suited for demodulation of very wideband signals, especially in digital predistortion (DPD) applications. The outstanding dynamic range of the LTC5586 makes the device suitable for demanding infrastructure direct conversion applications. Proprietary technology inside the LTC5586 provides the capability to optimize OIP2 to 80d Bm, and achieve image rejection better than 60d B. The DC offset control function allows nulling of the DC offset at the A/D converter input, thereby optimizing the dynamic range of true zero-IF receivers that use DC coupled IF signal paths. The wideband RF and LO input ports make it possible to cover all the major wireless infrastructure frequency bands using a single device. The IF outputs of the LTC5586 are designed to interface directly with most mon A/D converter input interfaces. The high OIP3 and high...
