CHR3364-QEG
17-24GHz Down Converter
Notes
Due to ESD protection circuits on RF and LO input, 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 (10nF) on the PC board, as close as
possible to the package.
Biasing Options
In order to improve the conversion gain or the input IP3, the biasing could be tuned.
VGL voltage allows controlling IDL current.
