The LTC5542IUH#TRPBF is part of a family of high dynamic range, high gain, passive downconverting mixers covering the 600MHz to 4GHz frequency range. The LTC5542IUH#TRPBF is optimized for 1.6GHz to 2.7GHz RF applications. The LO frequency must fall within the 1.7GHz to 2.5GHz range for optimum performance. A typical application is a LTE or WiMAX receiver with a 2.3GHz to 2.7GHz RF input and low-side LO.
The LTC5542IUH#TRPBF 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 LTC5542’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.
