Calculate even mode impedance of differential PCB transmission line



zeven = getZEven(txline,frequency) calculates the even mode impedance of the transmission line at the specified frequency.


collapse all

Create a coupled microstrip line with copper traces.

txline = coupledMicrostripLine;
txline.Conductor.Name = 'Copper';
txline.Conductor.Conductivity = 5.8e7;
txline.Conductor.Thickness = 0.001;

Calculate the even mode impedance of coupled microstrip line at 1 GHz.

freq = 1e9;
evenImp = getZEven(txline,freq)
evenImp = 49.1537

Input Arguments

Transmission line, specified as a coupledMicrostripLine, microstripLine, or microstripLineCustom object.

Example: txline = microstripLine;getZEven(txline). Calculates the even mode impedance of the microstrip transmission line object with handle txline.

Data Types: char | string

Frequency to calculate the even mode impedance, specified as a positive scalar in hertz.

Output Arguments
