LTC5548IUDB#TRPBF

LTC5548IUDB#TRPBF is a high-performance, microwave double-balanced passive mixer that can be used for frequency upconversion or downconversion. This device is similar to the LTC5549, but with a broadband, differential DC to 6GHz IF port. The LTC5548 is recommended for applications where the IF frequency range extends below 500MHz. For applications where the IF frequency is always above 500MHz, the LTC5549 is recommended, since it includes an integrated IF balun. The LTC5548’s mixer and integrated RF balun are optimized to cover the 2GHz to 14GHz RF frequency range. The device includes an integrated LO amplifier optimized for the 1GHz to 12GHz frequency range, requiring only 0dBm drive. The device also includes an integrated LO frequency doubler, which can be enabled or disabled with a CMOS-compatible control pin. Applications include microwave transceivers, wireless backhaul, point-to-point microwave, phased-array antennas, C, X and Ku band RADAR, test equipment, satellite MODEMs.
