Description

The LTC®5594 is a direct conversion quadrature demodulator optimized for high linearity zero-IF and low-IF receiver applications in the 300MHz to 9GHz frequency range. The very wide IF bandwidth of more than 1GHz makes the LTC5594 particularly suited for demodulation of very wideband signals, especially in 5G fronthaul/backhaul receiver applications. The outstanding dynamic range of the LTC5594 makes the device suitable for demanding infrastructure direct conversion applications. Proprietary technology inside the LTC5594 provides the capability to optimize OIP2 to 65dBm, 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 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 LTC5594 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.
