The LTC5541IUH#PBF is part of a family of high dynamic range passive, high gain downconverting mixers covering the 600MHz to 4GHz frequency range. The LTC5541IUH#PBF is optimized for 1.3GHz to 2.3GHz RF applications. The LO frequency must fall within 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 LTC5541IUH#PBF 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.
