Typical applicaTion
FeaTures DescripTion
Dual 1.3GHz to 2.3GHz
High Dynamic Range
Downconverting Mixer
The LTC
®
5591 is part of a family of dual-channel high dy-
namic range, high gain downconverting mixers covering
the 600MHz to 4.5GHz RF frequency range. 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.
