Product details

The LTC5586IUH is a direct conversion quadrature demodulator optimized for high linearity zero IF and low IF receiver applications in the frequency range from 300MHz to 6GHz. The very wide IF bandwidth (over 1GHz) makes the LTC5586IUH particularly suitable for demodulation of very wideband wide signals, especially in digital predistortion (DPD) applications.

The LTC5586IUH's excellent dynamic range makes the device suitable for demanding infrastructure direct conversion applications. The proprietary technology used within the LTC5586IUH provides the ability to optimize OIP2 to 80dBm and achieve mirror frequency rejection better than 60dB. The DC offset control function provides zeroing of the DC offset at the A/D converter input, thereby optimizing the dynamic range of a true zero IF receiver with a DC coupled IF signal path. Broadband RF and LO input ports enable coverage of all major wireless infrastructure bands with a single device.

The LTC5586IUH's IF output is designed to interface directly with most common A/D converter input interfaces. The device's high OIP3 and high conversion gain eliminate the need for additional amplifiers in the IF signal channel.
