L1 = 82 nH
C1 = 33 pF
L2 = 56 nH
C2 = 39 pF
C3 = 1,2 pF
All other components are 0 Ω jumpers.
The matching on the PCB does slightly differ from the theoretical matching. The reason for
that are parasitics of the PCB.
If the parasitics on the customer board (mentioned parasitics, additional parasitics of active
parts) are different to this PCB the matching elements have to be slightly adjusted.
