Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would
be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate
that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views.
It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if
you would like to post something on RF Cafe's

I am working on calculating the inductance and Q of some spiral inductors. These inductors are modeled using Momentum from Agilent.
A Momentum example gives the following procedure -
(1) Convert the S-Parameters to Z-Parameters using
(2) Convert the 2 port Z-parameters to a 1 port Z-parameters. Agilent states that Port 2 is considered to be grounded.
Then use the real and imaginary parts to determine the inductance and resistance.
The question I have is in step 2.
I come up with the equation
Where did I go wrong?
