CHR3662-QDG
7-16GHz Down Converter
Notes
Due to ESD protection circuits on RF and LO inputs, an external capacitance might be
requested to isolate the product from external voltage that could be present on these
accesses. ESD protections are also implemented on gate accesses.
The DC connections do not include any decoupling capacitor in package, therefore it is
mandatory to provide a good external DC decoupling on the PC board, as close as possible
to the package.
Refer to the application note AN0020 available at http://www.ums-gaas.com for general ESD
recommendations.
