Product Overview

The LT5557EUF#PBF is a 400MHz to 3.8GHz 3.3V Active Down-converting Mixer for high linearity 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 50Ω interfaces. The differential IF output allows convenient interfacing to differential IF filters and amplifiers or is easily matched to drive a single-ended 50Ω load, with or without an external transformer. The RF input is internally matched to 50Ω from 1.6 to 2.3GHz and the LO input is internally matched to 50Ω from 1 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 LT5557's high level of integration minimizes the total solution cost, board space and system-level variation.
