DescripTion
The LTC
namic range, high gain downconverting mixers covering
the 600MHz to 4GHz RF frequency range. The LTC5590
is optimized for 600MHz to 1.7GHz RF applications. The
LO frequency must fall within the 700MHz to 1.5GHz
range for optimum performance. A typical application
is a LTE or GSM receiver with a 700MHz to 915MHz RF
input and high side LO.
The LTC5590’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.
