DESCRIPTION
The LTC®5542 is part of a family of high dynamic range passive downconverting mixers covering the 700MHz to 4GHz frequency range. The LTC5542 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.
