Description
This pad is AC coupled and matched to
50 Ohms from 31 to 38 GHz.
This pad is AC coupled and matched to
50 Ohms from 31 to 38 GHz.
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 pad
must not source/sink more than 3mA of current or
die non-function and possible die failure will result.
Pads 5 and 6 are alternate IF ports.
The backside of the die must be connected
to RF/DC ground.
