getz0

Calculate characteristic impedance of RFCKT transmission line object

Syntax

z0 = getz0(txline)

Description

z0 = getz0(txline) returns the characteristic impedance z0, of a transmission line object txline.

Examples

Get Z0 of Network Object

Create and analyze a two-wire network object.

 tx1=rfckt.twowire('Radius',7.5e-4)

tx1 = 
   rfckt.twowire with properties:

            Radius: 7.5000e-04
        Separation: 0.0016
               MuR: 1
          EpsilonR: 2.3000
       LossTangent: 0
         SigmaCond: Inf
        LineLength: 0.0100
          StubMode: 'NotAStub'
       Termination: 'NotApplicable'
             nPort: 2

 analyze(tx1,1.9e9)

ans = 
   rfckt.twowire with properties:

            Radius: 7.5000e-04
        Separation: 0.0016

             nPort: 2
    AnalyzedResult: [1×1 rfdata.data]
              Name: 'Two-Wire Transmission Line'

Find the Z0 of the two-wire object.

 z0 = getz0(tx1)

z0 = 
31.4212

Input Arguments

txline — Transmission line

rfckt.txline object (default)

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

z0 — Characteristic impedance of transmission lines
