GENERAL DESCRIPTION The ADL5355 uses a highly linear, doubly balanced passive mixer core along with integrated RF and LO balancing circuitry to allow for single-ended operation. The ADL5355 incorporates an RF balun, allowing for optimal performance over a 1200 MHz to 2500 MHz RF input frequency range using low-side LO injection for RF frequencies from 1700 MHz to 2500 MHz and www.DataSheet4U.com high-side LO injection for RF frequencies from 1200 MHz to 1700 MHz. The balanced passive mixer arrangement provides good LO-to-RF leakage, typically better than −39 dBm, and excellent intermodulation performance. The balanced mixer co...
