FEATURES  
DESCRIPTION  
The LTC®5543 is part of a family of high dynamic range  
passive downconverting mixers covering the 700MHz to  
4GHzfrequencyrange.TheLTC5543isoptimizedfor2.3GHz  
to4GHzRFapplications.TheLOfrequencymustfallwithin  
the 2.4GHz to 3.6GHz range for optimum performance. A

The LTC5543 is designed for 3.3V operation, however; the  
IF amplifier 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 filters in high-selectivity  
receiver designs, while minimizing the total solution cost,  
board space and system-level variation.
