Hi,
I am new in the RF field and I have a question regarding Pi Networks and S parameters.
I was recently reading an article about Pi networks and it uses in RF. I am confused about a couple of things. The article said the k=1/S21, where k is the attenuation constant. How do you derive this relation between k and S21. I know that k=10^(A/20), where A is the value of attenuation, does it have something to do with this?
My second question is, the article says that the load reflection coefficient gammaL=1/k^2. How do I derive this?
Thanks, Nam
