DEMO MANUAL DC1710A-C LTC5592 Dual 1.6GHz to 2.7GHz High Dynamic Range Downconverting Mixer Description Demonstration circuit 1710A-C is a dual 1.6GHz to 2.7GHz The LTC5592s high conversion gain and high dynamic high dynamic range downconverting mixer featuring range enable the use of lossy IF filters in high-selective the LTC 5592. The LTC5592 is part of a family of dual- receiver designs, while minimizing the total solution cost, channel high dynamic range, high gain downconverting board space and system-level variation. mixers covering the 600MHz to 4.5GHz frequency range. High Dynamic Range Dual Downconverting Mixer Family The demo circuit 1710A-C and the LTC5592 are optimized DEMO IC PART RF RANGE LO RANGE for 1.6GHz to 2.7GHz RF applications. The LO frequency DC1710A-A LTC5590 600MHz to 1.7GHz 700MHz to 1.5GHz must fall within the 1.7GHz to 2.5GHz range for optimum DC1710A-B LTC5591 1.3GHz to 2.3GHz 1.4GHz to 2.1GHz performance. A typical application is a LTE or WiMAX DC1710A-C LTC5592 1.6GHz to 2.7GHz 1.7GHz to 2.5GHz receiver with a 2.3GHz to 2.7GHz RF input and low side LO.
