Yes, but above 5 Ghz we are talking ultra hi freq.

You never know if he is talking about 5 or 40 or even automotive radar that could be 24 or 77.

High frequency RF is considered to be above 1 ghz, generally speaking. Not sure if this is formalized somewhere?

Re: [TN] Low Loss PCB Material
Hi, Ravinder
You might want to look at the following:
Nelco N4000-13EP
Panasonic Megtron Getek
Taconic RF-35TC or RF35A2
I know these are all RF-tailored, but not sure if all are halogen free. I
know the Taconic materials are.
You would need to check with them about the UL approval rating.

Hi All,
We discussed with our quick-turn fab the use of low-loss PCB materials for
high-speed applications. As per the discussions,the only such material
that is Halogen-Free and has UL Approval seems to be Rogers Theta
material. If there are other materials available in US and more
importantly at the high-volume fabs off-shore then please share the
information. I will really appreciate it.
Thanks.
