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
page, please do.
Below are all of the forum threads, including all

I am a beginner
in designing a RF IMPEDANCE STANDARD For calibration.
As my assignment/project required me to design a
IMPEDANCE STANDARD substrate for TRL calibration at high frequency for the probe operating from 140GHz-220GHz.
I hope you all can suggest to me which websites and books suitable for me to learn how to design the IMPEDANCE
STANDARD for high frequency calibration and testing.
Hope for the reply soon, thank you very much.

I would go
to the Agilent website and look for a application note on TRL calibration. The standards are pretty straight
forward, nut you need to be careful what the wavelenght is. Also, the Anritsu website has a good application note
on the subject.
