How to test insert loss of the Balun? Thanks!

[dopradar]

Hi all,

How to use single-end port network analyzer to test balun---single end to differential ports?

I have tested three pieces of 2-port S-parameter with three different port loading separately, so there is a question, how to use these parameters to calculate the insert loss of balun?

Are there some papers/documents to introduce this issue? Thanks!

Best Regards!

If you have two balun connect on ethe opposite of the other and divide the attenuation by 2.
