Note: external components are requested in order to use the part properly: on RF input
access a DC block is requested, on RF output access a Bias Tee is requested.
Depending on the board, additional capacitors such as 1µF may be added on Vg1 or Vg2
access if necessary, for better low frequency decoupling.
Smaller capacitors than 470nF could be use if the part is not use in low frequency range
(< 1 GHz): 10nF.
