RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling
2 MB. Its primary purpose was to provide me with ready access to commonly needed
formulas and reference material while performing my work as an RF system and circuit
design engineer. The World Wide Web (Internet) was largely an unknown entity at
the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps
while tying up your telephone line, and a nice lady's voice announced "You've Got
Mail" when a new message arrived...

IMPEDANCE STANDARD For calibration - RF Cafe Forums
RF Cafe Forums closed its virtual doors in 2012 mainly due to other social media
platforms dominating public commenting venues. RF Cafe Forums began sometime around
August of 2003 and was quite well-attended for many years. By 2010, Facebook and
Twitter were overwhelmingly dominating online personal interaction, and RF Cafe
Forums activity dropped off precipitously. If the folks at
phpBB would release a version with integrated
sign-in from the major social media platforms, I would resurrect the RF Cafe Forums,
but until then it is probably not worth the effort. Regardless, there are still
lots of great posts in the archive that ware worth looking at.

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
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.

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.
