... The LTC 5593 is part of a family of dual-channel high dy- ® namic range, high gain downconverting mixers covering the 600MHz to 4.5GHz RF frequency range. The LTC5593 is optimized for 2.3GHz to 4.5GHz RF applications. The LO frequency must fall within the 2.1GHz to 4.2GHz range for optimum performance. A typical application is a LTE or WiMAX multichannel or diversity receiver with a 2 ...
