DESCRIPTION
The LTC®5543 is part of a family of high dynamic range passive downconverting mixers covering the 700MHz 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.
