TYPICAL APPLICATION
DESCRIPTION
2.3GHz to 4GHz
High Dynamic Range
Downconverting Mixer
The LTC
®
5543 is part of a family of high dynamic range, high
gain passive downconverting mixers covering the 600MHz to
4GHz frequency range. The LTC5543 is optimized for 2.3GHz
to 4GHz RF applications. The LO frequency must fall within
the 2.4GHz to 3.6GHz range for optimum performance. A
typical application is a LTE or WiMAX receiver with a 2.3GHz
to 2.7GHz RF input and high-side LO.
The LTC5543 is designed for 3.3V operation, however; the
IF amplifi er can be powered by 5V for the highest P1dB.
An integrated SPDT LO switch with fast switching accepts
two active LO signals, while providing high isolation.
The LTC5543’s high conversion gain and high dynamic
range enable the use of lossy IF fi lters in high-selectivity
receiver designs, while minimizing the total solution cost,
board space and system-level variation.
