After entering the model parameters, click Analyze and Channel Designer will compute the frequency
response of the current design. The integrated plotting engine can display the insertion loss or return
loss characteristics. When you alter the model parameters, the GUI displays a message that indicates the
channel characteristics may have changed. Click Analyze to redraw the channel characteristics. You can
also load or save the component design for reuse in the future.
If you are satisfied with your design, click OK to save and close the component design GUI. If you click
Exit or the X button of the window, the design will be discarded.
RLGC Transmission Line Component
The channel will be constructed with unit length RLGC models. A typical RLGC transmission line
structure is shown in the following figure with these parameters:
• Input parameters
• L—Unit Length inductance (in various units)
• Rdc—Unit length DC resistance (in various units)
• Rac—Unit length skin-effect resistance (in various units)
• C—Unit length capacitance (in various units)
• Gdc—Unit length DC conductance (in various units)
• Gac—Unit length AC conductance (in various units)
• Length—Length of the coax (in various units)
• Freq—Frequency where the Z0 (Impedance) and E-Eff (electrical length) are reported (in various
units)
• Output parameters
• Z0—Impedance at specified frequency Freq (Ohm)
• E-Eff—Electrical length (in various units)
