FEATURES
DESCRIPTION
TheLTC®5541ispartofafamilyofhighdynamicrangepassive
downconverting mixers covering the 700MHz to 4GHz
frequency range. The LTC5541 is optimized for 1.3GHz to
2.3GHzRFapplications.TheLOfrequencymustfallwithin
the 1.4GHz to 2.0GHz range for optimum performance.
A typical application is a LTE or W-CDMA receiver with a
1.7GHz to 2.2GHz RF input and low-side LO.

The LTC5541 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 LTC5541’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.
