Note :
The balanced - balanced network is realized using TOKO 1:1 baluns B5FL. The insertion attenuation of each balun is 0,6 dB at fN. The loss of the baluns is not included in the specified filter
insertion attenuation.
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 our application note PCB Layout for Highly Selective IF Filters.
