John,
all:
But
does a line made with the squared and cubed terms create a physically
realizable channel?
In
the real channel I think there may be only two variables to play with:
skin effect and dielectric
absorption. If we base simulations
on something other than this, then I think bad things can happen like
non-causal effects.

Guys,
Goergen asked the magic question. Is
it possible? Yes it is. We have a squared and cubed term to play
with. I am hoping Joel has some suggestions as well. I just had a
chance to do a quick scan and saw this. I will be working on this stuff
tonight
John

I see now what you refer
too. I am not sure how you physically relaize a channel you are suggesting,
keep low freq the same and come up at 5 GHz? Any physical channel should result
in a tilted line?

The line didn’t only tilt. It also shifted. John D looked
at a few channels as I attached. If we shift, it’s got an impact for KX
and KX4.

The new channel appears to be inline with what we stated - a tilt of the
line from DC to about a 3dB drop at 5GHz. Why do you feel the lower
frequencies need to stay fixed?
Thanks, Joe

Hi Charles,
DC and low freq's went down way to much! Can you create a model with the
same losses at say 1GHz or so and 2 dB less at 5GHz? I thought that's
what we agreed.

guys,
I propose that we use the model ITTC_23.s4p for reduced
attenuation
EIT modeling. If it really will not work, ITTC_20.s4p is available as a
bail out channel. If it looks too easy, let me know and i will step it
up just
a tad.
The numbers refer to the fitted attenuation at 5.15...GHz.
