Lecture -- Quadrature Hybrid Coupler

[@ramtinnaji1572]

Great presentation. where does this formula come from for even reflection coefficient on minute 8:32? (A+B-C-D)/(A+B+C+D)

[@erikmjelde4428]

Perfect summary of this topic. Thanks!

[@empossible1577]

Thank you!

[@azozaya]

Good summary. The matrix factor shouldn't be -1/sqrt(2) instead of - j/sqrt(2)?

[@manamohammed4470]

If we change the input port to port 4 , will the sign of phase shifts at the output ports change accordingly,?

[@reltius2993]

I never saw odd/even analysis before in my EE background so this gave some idea of what it was and how it works, although I'd like to see more detail. Do you have another video explaining more how to derive matrices in more detail?

[@empossible1577]

That is a good idea. It may have to wait until I teach this course again. Thank you!

[@mharinathreddy8262]

For the odd mode analysis, along the axis, is the line symmetric or antisymmetric ?
Thanks

[@Shler-yahya]

Why there is a "J" phase in some of the scattering parameters for the Directional Coupler ?

[@empossible1577]

Hybrid couplers introduce 90 phase. The j terms are 90 degrees phase.

Great great 👍

[@serBarcla]

Thank you. summarised quite well. Can you please do 7.6

[@empossible1577]

7.6 what?
