The LTC5591 is optimized for 1.3GHz to 2.3GHz RF applications. The LO frequency must fall within the 1.4GHz to 2.1GHz range for optimum performance. A typical application is a LTE or W-CDMA multichannel or diversity receiver with a 1.7GHz to 2.2GHz RF input and low side LO. The LTC5591’s high conversion gain and high dynamic range enable the use of lossy IF filters in high selectivity receiver designs, while minimizing the total solution cost, board space and system-level variation. A low current mode is provided for additional power savings and each of the mixer channels has independent shutdown control.
