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.

The DC connections do not include any decoupling capacitor in package, therefore it is
mandatory to provide a good external DC decoupling (100pF, 10nF, 1µF) on the PC board,
as close as possible to the package.
A 10KΩ resistor is recommended in parallel to VDET, and VREF accesses.
The circuit includes ESD protections on all RF and DC accesses.
