Overview

The LTC5586IUHPBF 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 LTC5586IUHPBF particularly suited for demodulation of very wide-band signals, especially in Digital Pre-Distortion (DPD) applications. The outstanding dynamic range of the LTC5586IUHPBF makes the device suitable for demanding infrastructure direct conversion applications. Proprietary technology inside the LTC5586IUHPBF 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. The wide-band 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 LTC5586IUHPBF are designed to interface directly with most common A/D converter input interfaces. The high OIP3 and high conversion gain of the device eliminate the need for additional amplifiers in the IF signal path.
