TYPICAL APPLICATION
FEATURES DESCRIPTION
Dual 2.3GHz to 4.5GHz
High Dynamic Range
Downconverting Mixer
The LTC
®
5593 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 LTC5593
is optimized for 2.3GHz to 4.5GHz RF applications. The
LO frequency must fall within the 2.1GHz to 4.2GHz
range for optimum performance. A typical application is
a LTE or WiMAX multichannel or diversity receiver with a
2.3GHz to 2.7GHz RF input.
The LTC5593’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.
