LTC5549IUDB#TRMPBF

LTC5549 is a general purpose passive double balanced mixer that can be used for upconversion or down conversion. The RF port is designed for the 2GHz to 14GHz band and the IF port is optimized for 500MHz to 6GHz operation. An integrated LO buffer amplifier supports LO frequencies from 1GHz to 12GHz, requiring only 0dBm LO power. It delivers high IIP3 and input P1dB with low power consumption. An internal LO frequency doubler can be enabled by a CMOS-compatible digital control pin, allowing operation with a lower, one-half LO input frequency. This allows the mixer’s LO port to be used with existing synthesizers, such as the LTC6946 and LTC6948 family. It is used in application such as microwave transceivers, wireless backhaul, point-to-point microwave, phased-array antennas, C, X and Ku Band RADAR, test equipment, satellite MODEMs.
