Units of parameters in lossy transmission lines?

Zhengzhi Wang

I am trying to use the lossy transmission line model in PSpice. As shown in the figure, the key parameters are C, G, L, LED, R. What are their units?

    For a lossy line, LEN is the electrical length. R, L, G, and C are the per unit length values of resistance, inductance, conductance, and capacitance, respectively.

    LEN is electrical length. It can be in any unit, like feet, meters etc.

    If LEN is in meter,  R unit would be Ohm/meter and so on. Similarly L would be Henry/meter.

    Hope this helps.
