Linear Technology
DESCRIPTION
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 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.
