Shielded Twisted Pairs cable model

[cpereira]

Hello,

I am trying to simulate a Shielded Twisted Pairs cable.

Can anyone tell me what is the best model to use on Pspice ?

The cable has the following characteristics:

Conductor Resistance: 37,5 ohm/km

Mutual Capacitance: 80 nF/km

Attenuation at: 1MHz = 3.3dB/km | 10MHz = 7.5 db/km

Insulation resistance: bigger than 10 Gohm/km

Thanks in advance

Hi.

PSpice has the Tline library. there are models of twisted pairs from 19 awg to 26awg. The models are characterized by 4 parameters that vary with the frequency r Ohm/meter, l Henries/meter, g Mhos/meter c Farads/meter and the length.
