Typical Application
Description
The LT5526 is a low power broadband mixer optimized for high linearity applications such as point-to-point data transmission, cable infrastructure and wireless infrastructure systems. The device includes an internally matched high speed LO amplifier driving a double-balanced active mixer core. An integrated RF buffer amplifier provides excellent LO-RF isolation. The RF and IF ports can be easily matched across a broad range of frequencies for use in a wide variety of applications.The LT5526 offers a high performance alternative to passive mixers. Unlike passive mixers which have conversion loss and require high LO drive levels, the LT5526 delivers conversion gain at significantly lower LO input levels and is much less sensitive to LO power level variations.
