Randy,

Unlike FR4, cyanate ester, PPO, the DK of PTFE laminates does not change much over frequency, not even in the
Gigahertz range. My mail you will receive a Taconic data pack that contains contains graphs of DK vs.
Frequency, Loss vs. Frequency, etc. of the whole Taconic range.

You can also access these data sheet on the Taconic web site (www.4taconic.com), if you have the Adobe 3.0
reader installed.

Does anyone have any sources of info on high-frequency dielectic
constant for circuit materials, especially how it varies with frequency?
I'm interested in the megahertz and gigahertz ranges.  Thanks!
