Find the Z0 of the two-wire object.

 z0 = getz0(tx1)
z0 = 31.4212

Input Arguments

collapse all

Transmission lines object to analyze, specified as a rfckt.txline handle.

Example: txline = rfckt.txline;getz0(txline). Calculates the characteristic impedance of the transmission line object with handle txline.

Data Types: char | string

Output Arguments

collapse all

Characteristic impedance of the transmission line, returned as a complex scalar.

Data Types: double
