17–24 GHz 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 in the application.

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.
