Description
Power supply for the LO Amplifier. An external RF bypass
capacitor of 100 - 330 pF is required. A MIM border capacitor
is recommended. The bond length to the capacitor should be
as short as possible. The ground side of the capacitor should
be connected to the housing ground.
This pad is AC coupled and matched
to 50 Ohm.
This pad is DC coupled and should be DC blocked externally
using a series capacitor whose value has been chosen to pass

IF
the necessary IF frequency range. Any applied DC voltage to
this pin will result in die non-function and possible die failure.
