The is a 2 to 14GHz Microwave Mixer with integrated LO frequency doubler. The LTC5549 is a general purpose passive double balanced mixer that can be used for up-conversion or down-conversion. The RF port is designed for the 2 to 14GHz band and the IF port is optimized for 500MHz to 6GHz operation. An integrated LO buffer amplifier supports LO frequencies from 1 to 12GHz, requiring only 0dBm LO power. The LTC5549 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.
