Note :
The level of ultimate suppression may be limited by electromagnetic feedthrough depending on
the layout of the pcb and the arrangement of the matching components.
The above mentioned characteristics can be realized either in balanced or in unbalanced mode
of operation.
For more details see S+M’s application note
PCB Layout for Highly Selective IF Filters.
