Overview
The ADMV1014ACCZ-R7, produced by Analog Devices Inc., is a silicon germanium (SiGe) wideband microwave downconverter. It is optimized for point-to-point microwave radio designs operating within the 24 GHz to 44 GHz frequency range. This device offers two primary modes of frequency translation: direct conversion from RF to baseband I/Q signals and image rejecting downconversion to a complex intermediate frequency (IF) output carrier frequency. The ADMV1014 is designed to provide high performance and flexibility in microwave radio systems.
