LTC5586IUH#PBF

LTC5586 is a direct conversion quadrature demodulator optimized for high linearity zero-IF and low IF receiver applications in the 300MHz to 6GHz frequency range. The very wide IF bandwidth of more than 1GHz makes the device particularly suited for demodulation of very wideband signals, especially in digital predistortion (DPD) applications. The outstanding dynamic range of the device makes the device suitable for demanding infrastructure direct conversion applications. Proprietary technology inside the device provides the capability to optimize OIP2 to 80dBm, and achieve image rejection better than 60dB. 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. It is used in application like 4G and 5G base station receivers, wideband DPD receivers, point-to-point broadband radios, high linearity direct conversion I/Q receivers.
