$)CLCP films have low permeability and loss tangent around .003, and can be
processed into 1 metal layer and 2 metal layer substrates. Dielectric
thicknesses are typically 25 and 50 micron, but can be thinned down below
15 microns.
I can provide more information upon request.
Thanks,

Hi Experts!
I am looking for the substrate can be used more than 40 GHz with low
relative permeability and loss tangent.
I would like to design grounded CPW with the substrate.
The substrate thickness is considered to be as small as order of tens of
micrometer.
So far, I have used alumina, but it's relative permeability is so large
that cavity resonance often occurred in my design.
Hope to get a good news from you...
Regards,
Kwang-Seong Choi
