DESCRIPTIOU
The LT
5526 is a low power broadband mixer optimized
for high linearity applications such as point-to-point data
transmission, cable infrastructure and wireless infrastruc-
ture 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 conver-
sion 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.
