The device includes an internally 50Ω matched high speed LO amplifier driving a double-balanced active mixer core. An integrated RF buffer amplifier provides excellent LO-RF isolation. The RF input balun and all associated 50Ω matching ponents are integrated. The IF ports can be easily matched across a broad range of frequencies for use in a wide variety of applications. 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. , LTC and LT are registered trademarks of Linear Technology Corporation. - Operation over a wider frequency range is achievable with reduced performance.
