Quarter Wave Transformers — Lesson 9

[tsjoung]

Thank you for very helpful and well-explained lecture!

I just found a typo at 1:01.
I think the expression for Z_in should be
Z_1 * (Z_L + j*Z_1*tan(beta*l)) / (Z_1 + j*Z_L*tan(beta*l))
instead of
Z_o * (Z_L + j*Z_1*tan(beta*l)) / (Z_1 + j*Z_L*tan(beta*l))

It's just a minor typo, but hope this correction helps someone who gets confused like me ;)

It doesn't really prevent reflexion, isn't there still reflexion due to the discontinuity on the line?
