txlineDelayLossless

Create delay lossless transmission line

    Description

    Use the txlineDelayLossless object to create a delay lossless transmission line. You can also use the txlineDelayLossless object to model a delay lossless transmission line in an RF system using the rfbudget object or the RF Budget Analyzer app.

    Creation

    Description

    dltxline = txlineDelayLossless creates a default delay lossless transmission line object.

    example

    dltxline = txlineDelayLossless(Name,Value) sets Properties of the delay lossless transmission line using one or more name-value arguments. For example, dltxline = txlineDelayLossless('Z0',75) creates a delay lossless transmission line with an impedance of 75 ohms.

    Properties

    expand all

    Name of the delay lossless transmission line, specified as a string scalar or character vector.

    Example: 'Name','DLbased'

    Example: dltxline.Name = 'DLbased'

    Characteristic impedance of the delay lossless transmission line, specified as a positive scalar in ohms.

    Example: 'Z0',75

    Example: dltxline.Z0 = 75

    Time delay in the delay lossless transmission line, specified as a positive scalar in seconds.

    Example: 'TimeDelay',1e-9

    Example: dltxline.TimeDelay = 1e-9

    This property is read-only.

    Number of input and output ports of the delay lossless transmission line, returned as positive scalar.

    This property is read-only.

    Terminals of the delay lossless transmission line, returned as a cell array.

    Examples

    collapse all

    Create a delay lossless transmission line with a transmission delay of 5e-12 sec.

    dltxline = txlineDelayLossless('TimeDelay',5e-12);

    Calculate the group delay at 10 MHz.

    gd = groupdelay(dltxline,10e6)
    gd = 5.0000e-12
    

    Calculate the noise figure at 10 MHz.

    nf = noisefigure(dltxline,10e6)
    nf = 0
