Die Bottom
This pin is DC coupled
RF
and matched to 50 Ohms.
IF
GND
This pad is DC coupled. For applications not requiring
operation to DC, this port should be DC blocked externally
using a series capacitor whose value has been chosen to
pass the necessary IF frequency range. For operation to DC,
this pin must not source or sink more than 2 mA of current or
part non-function and possible part failure will result.
Die bottom must be connected to RF/DC ground.
