Quarter Wave Transformers - Lesson 9

This video lesson discusses a quarter-wave-long section of a transmission line with a characteristic impedance that can be added to the transmission line to maximize energy transfer to the load. It is part of the Ansys Innovation Course: Transmission Line Theory.

This course was created for Ansys Innovation Courses by Kathryn Leigh Smith, Assistant Professor, UNC-Charlotte in partnership with Ansys.

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 ;)

You're quite right - I mixed my terminology. Thank you!

please correct the mistakes in formula , instead of Z1 its shown Z0 (@1:12)

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

can anyone tell me what is Zo,Z1 &Z2 ?
