21-29.5GHz Medium Power Amplifier
CHA3395-QDG
Notes
Due to ESD protection circuits on RF input and output, an external capacitance might be
requested to isolate the product from external voltage that could be present on the RF
accesses.
ESD protections are also implemented on all DC 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.
