Conversion Gain: 8.3dB at 2.35GHz
The LTC®5592 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 LTC5592
is optimized for 1.6GHz to 2.7GHz RF applications. The
LO frequency must fall within the 1.5GHz to 2.5GHz
range for optimum performance. A typical application
is a LTE or WiMAX receiver with a 2.3GHz to 2.7GHz RF
input and low side LO.

Independent Channel Shutdown Control
The LTC5592’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.
