Typical Application
Description
The LT5527 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 single ended 50Ω interfaces. The differential IF output allows convenient interfacing to differential IF filters and amplifiers,or is easily matched to drive 50Ω single-ended, with or without an external transformer.The RF input is internally matched to 50Ω from 1.7GHz to3GHz, and the LO input is internally matched to 50Ω from1.2GHz 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 LT5527’s high level of integration minimizes the total solution cost, board space and system-level variation.
