LT5557 - 400MHz To 3.8GHz 3.3V High Linearity Downconverting RF Mixer

The LT5557 active mixer is optimized for high linearity, wide dynamic range downconverter 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 singleended 50 Interfaces The differential IF output allows convenient interfacing to differential IF Filters and Amplifiers or is easily matched to drive a single-ended 50 load, with or without an external transformer. The RF input is internally matched to 50 from 1.6GHz to 2.3GHz, and the LO input is internally matched to 50 from 1GHz 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.
The LT5557s high level of integration minimizes the total solution cost, board space and system-level variation.
