LT5525 - High Linearity, Low Power Downconverting Mixer

The LT5525 offers a high performance alternative to passive mixers. Unlike passive mixers, which require high LO drive levels, the LT5525 operates at significantly lower LO input levels and is much less sensitive to LO power level variations.

*Operation over a wider frequency range is achievable with reduced performance.  Consult factory for more information.
