3. Matching on the PCB
The matching network on the test board (PCB – tft027) was tested with SMD-components with Q-value
of
≈
50...70.

= 82 nH.
For scheme 1:
ILo (typ.) = - 24,0 dB
Pass band riplle (typ.) = 0,8...0,9 dB
Group delay ripple in pass band (typ.) = 160 ns (p-p
The matching networks on the PCB does slightly differ from the theoretical matching. The reasons for
that are parasitics of the PCB and of the transformers, and particularly differences in the Q-value of the
matching components. But if the parasitics on the customer board (mentioned parasitics, additional
parasitics of active parts) are different to this PCB, the matching elements will have to be slightly
adjusted. Both in line and shunt elements change both pass band shape (tilt) and insertion loss ILo.
