HFSS15: Via Model
Description - a model of a differential via pair. It has a pair of microstrip lines that transition through the vias to a pair of striplines on a lower layer. This model was created using the Via Wizard.*
Model - the two microstrip lines are each assigned a terminal in the coupled microstrip port. Likewise for the two striplines at the opposite end. The conductors are copper and a radiation boundary is applied to the air box.
Setup - adapt at 4.38 GHz with an interpolating sweep that has an upper frequency of 4.38 GHz and uses DC extrapolation at the lower end. Mixed Order is set for Order of Basis Function.
Note | To view a port or boundary, select the desired item in the Project Tree. It is then highlighted in the Model window and the properties will be displayed in the Properties window. Selecting an object in the History tree will also display its properties. |
