The transmission line is a balanced type with the input at one end and on one side only of the balanced transmission line and the output at the opposite end is also the opposite side of the balanced transmission line.

Equivalent circuit of a balanced transmission line ( such as twin-lead ) where : 2 / Z = trans-admittance of VCCS ( Voltage Controlled Current Source ), X = length of transmission line, Z ( s ) = characteristic impedance, T ( s ) = propagation function, ? ( s ) = propagation constant , s = j?, j?=-1.
