RF
This pad is DC coupled
and matched to 50 Ohms..
This pad is DC coupled. For applications not requiring oper-
ation to DC, this port should be DC blocked externally using
a series capacitor whose value has been chosen to pass the
3
IF
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.
GND
The backside of the die
must be connected to RF ground.
