The ADMV1018 from Analog Devices is an Up/Down Converter that operates from 24 to 29.5 GHz. It has an RF bandwidth of 1.5 GHz and operates as an Up/Down converter to support 5G NR frequency bands such as n257, n258, and n261.
This device has integrated LO doubler and quadrupler circuits. It offers two up conversion modes - direct conversion from differential baseband I/Q or single-ended complex IF with optimized IF range, to RF single sideband up conversion. And two down conversion modes - direct conversion from RF to differential baseband I/Q or image-reject down conversion/single-ended complex IF. It is available in an optimized package which is designed for good thermal performance.
