3. PCB matching
The following matching elements have been used on the PCB:
Input
C1
L1
1
SAW
L2
6
C2
7
2,3,4,5,8,9,10
L1 = 68 nH
C1 = 27 pF
LB-OUT
L2 = 6,8 nH
C2 = 10 pF
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 PCB are
different the matching elements have to be slightly adjusted.
