Don,

        You can try using software from HP-EEsof called LineCalc, which will
give you results of linewidth for a given impedance or an impedance for a given

linewidth depending on the construction (material, thickness, copper thickness)

and frequency. Also, from Rogers Corp. we have a program that can generate a
table based on linewidth/impedance which can then be plotted (this software is
free). If you are interested send me an email or call (602 961-1382). Thanks.

To: TechNet
     We are looking to upgrade our current Impedance calculation
     software. We are looking for what is currently on the
     market which will output a good graphical printout for
     out files and to send to our customers.

     Any feedback would be appreciated.
