3.20 T: Transmission Line
3.20.1 Syntax
Txxxxxxx n1+ n1– n2+ n2– {args}
.TLIne xxxxxxx n1+ n1– n2+ n2– {args}
3.20.2 Purpose
Lossless transmission line.
3.20.3 Comments
N1+ and n1– are the nodes at one end. N2+ and n2– are the nodes at the other end.
The parameters TD, Freq, and NL determine the length
of the line. Either TD or Freq and NL must be
specified. If only Freq is specified, NL is assumed to be
.25. The other will be calculated based on the one you specify. If
you specify too much, Freq and NL dominate, and a warning
is issued.
3.20.4 Element Parameters
- Z0 = x
- Characteristic impedance. (Default = 50.)
- TD = x
- Time delay.
- Freq = x
- Frequency for NL.
- NL = x
- Number of wavelengths at Freq.
