Derived parameters are: lm=4.40066e-09, ctot=5.45e-12. -* -* It is important to note that the model is a simplified one - the -* following assumptions are made: 1. The self-inductance l, the -* self-capacitance ctot (note: not c), the series resistance r and the -* parallel capacitance g are the same for all lines, and 2. Each line -* is coupled only to the two lines adjacent to it, with the same -* coupling parameters cm and lm. The first assumption imply that edge -* effects have to be neglected. The utility of these assumptions is -* that they make the sL+R and sC+G matrices symmetric, tridiagonal and -* Toeplitz, with useful consequences. -* -* It may be noted that a symmetric two-conductor line will be -* accurately represented by this model. - -* Lossy line models -.model mod1_conv2wtwentyinch ltra rel=1.2 nocontrol r=0.2 l=4.72933999088e-09 g=0 c=7.25000000373e-12 len=20 -.model mod2_conv2wtwentyinch ltra rel=1.2 nocontrol r=0.2 l=1.35306599818e-08 g=0 c=3.65000000746e-12 len=20 - -* subcircuit m_conv2wtwentyinch - modal transformation network for conv2wtwentyinch -.subckt m_conv2wtwentyinch 1 2 3 4 -v1 5 0 0v -v2 6 0 0v -f1 0 3 v1 0.707106779721 -f2 0 3 v2 -0.707106782652 -f3 0 4 v1 0.707106781919 -f4 0 4 v2 0.707106780454 -e1 7 5 3 0 0.707106780454 -e2 1 7 4 0 0.707106782652 -e3 8 6 3 0 -0.707106781919 -e4 2 8 4 0 0.707106779721 -.ends m_conv2wtwentyinch - -* Subckt conv2wtwentyinch -.subckt conv2wtwentyinch 1 2 3 4 -x1 1 2 5 6 m_conv2wtwentyinch -o1 5 0 7 0 mod1_conv2wtwentyinch -o2 6 0 8 0 mod2_conv2wtwentyinch -x2 3 4 7 8 m_conv2wtwentyinch -.ends conv2wtwentyinch - -.model convtwoinch ltra r=0.2 l=9.13e-9 c=3.65e-12 len=2.0 rel=1.2 nocontrol -.subckt conv2wetcmodel 1 2 3 4 -o1 1 0 5 0 convtwoinch -x1 5 2 6 4 conv2wtwentyinch -o2 6 0 3 0 convtwoinch -.ends conv2wetcmodel - -.end |
