New Original LTC5549 LTC5549IUDB LTC5549IUDB#TRMPBF LTC5549IUDB#TRPBF RF Mixer IC Radar 2GHz ~ 14GHz 12-QFN (3×2)

Large Quantities, Price Negotiable!

The LTC5549 is a versatile passive double-balanced mixer for upconversion or downconversion. The RF port is designed for operation in the 2 GHz to 14 GHz frequency band, while the IF port is optimized for 500 MHz to 6 GHz operation. An integrated LO buffer amplifier supports LO frequencies from 1 GHz to 12 GHz, requiring only 0 dBm LO power. The LTC5549 offers high IIP3 and input P1dB while maintaining low power consumption.
