Note
7- 16GHz High Power Amplifier
Due to ESD protection, RFin and RFout are DC grounded, an external capacitance might be requested to isolate the product from external voltage that could be present on the RF accesses.

RFin
23 Vd3 17
RFout
Vg1, 2 9
Vg3 Vd3 11 13
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.
Definition of the Sij reference planes
The reference planes are defined from the footprint of the recommended characterization board shown below under the number 96402. The reference is the symmetrical axis of the package. The input and output reference planes are located at 3.66mm offset (input wise and output wise respec.) from this axis. Then, the given Sij incorporates this land pattern.
