LT5527EUF#PBF

The LT5527EUF#PBF is a 400MHz to 3.7GHz 5V high signal level Down-converting Mixer optimized for high linearity, wide dynamic range down-converter applications. The IC includes a high speed differential LO buffer amplifier driving a double-balanced mixer. Broadband, integrated transformers on the RF and LO inputs provide single-ended 50R interfaces. The differential IF output allows convenient interfacing to differential IF filters and amplifiers or is easily matched to drive 50R single-ended, with or without an external transformer. The RF input is internally matched to 50R from 1.7 to 3GHz and the LO input is internally matched to 50R from 1.2 to 5GHz. The frequency range of both ports is easily extended with simple external matching. The IF output is partially matched and usable for IF frequencies up to 600MHz.
