It uses the equation in "Accurate Wide-Range Design Equations for the Frequency Dependent Characteristics...", Kirschning, Jansen, IEEE MITT Jan 1984, Page 83 onwards. The Effective Line Permittivity is from "Handbook of Microwave and Optical Components", Chang, Chapter 1, Table 1.16. This has a correction for line thickness. No calculation has been made for frequency as the dimensions are so small that dispersion will not cause a problem, Refer to sheet for Zo. The results are compared to ADS linecalc and are pretty close but up to 10% out for thick lines; thin lines are ok.7$<%8#0,0,1289&<':@W/(<):@W/&((1*</+<,0@NormalArial - COleDocItemDocItem @UvN ࡱ> DEFC   !"#$%&'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqrstuvwxyz{|}~Root Entry@96>@)@jCONTENTS yCONTENTSV30CompObju.WSF;.WSHPROCESSOR_ @96>@)#Microsoft Photo Editor 3.0 PictureMSPhotoEditor MSPhotoEd.39q%1D|n`%1
