Data Sheet
148,05 MHz
Recommended pin configurations / test matching networks:
a) single-ended 50Ω / single-ended 50Ω
LS1 = 150 nH
CP2 = 3,9 pF
CP3 = 3,9 pF
LS4 = 150 nH
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.
To achieve the best performance it is recommended to drive at least one side of the filter bal-
anced.
For more details see S+M’s application note PCB Layout for Highly Selective IF Filters.
