Hello,
I was reading the AAC article on stub matching
https://www.allaboutcircuits.com/technical-articles/learn-stub-tuning-with-a-smith-chart/
and I got stuck on the stub lengths at the double stub tuning example.
The author states that L1 = 0.146λ, L2 = 0.204λ or L’1 = 0.482λ, L’2 = 0.35λ.
But how do these value are determines from Smith chart ? I think I understand the way to calculate them for single stubs, but I don't see as the same method works for parallel stubs. Could someone clarify this ?
Thanks.
Regards.
