Data Sheet
Recommended pin configurations / test matching networks:
a) single-ended 50Ω / single-ended 50Ω
Input : Pin 10
Output : Pin 5
Ls1 = 100 nH
Cp2 = 3,9 pF
Cp3 = 3,9 pF
Ls4 = 100 nH
b) single-ended 50Ω / balanced 50Ω
Input : Pin 10
Output : Pins 5 and 4
Ls1 =100 nH
Cp1 = 3,9 pF
Cp2 = 3,9 pF
Ls2 =39 / 47 nH
Note :
The balanced network is realized using TOKO 1:1 balun B5FL. The insertion attenuation of a
balun is 0.6 dB at 183.6 MHz. The loss of the balun 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 EPCOS’s application note PCB Layout for Highly Selective IF Filters.
