DESCRIPTION
The LTC®5541 is part of a family of high dynamic range passive, high gain downconverting mixers covering the 600MHz to 4GHz frequency range.The LTC5541 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.
