GENERAL DESCRIPTION
The ADL5357 uses a highly linear, doubly balanced passive mixer core along with integrated RF and LO balancing circuitry to allow for single-ended operation. The ADL5357 incorporates an RF balun, allowing for optimal performance over a 500 MHz to 1700 MHz RF input frequency range using high-side LO injection for RF frequencies from 500 MHz to 1200 MHz and low-side www.DataSheet4U.com injection for frequencies from 900 MHz to 1700 MHz. The balanced passive mixer arrangement provides good LO-to-RF leakage, typically better than −46 dBm, and excellent intermodulation performance. The balanced mixer core also...
