Filter Coupled Line - Visualize and Analyze
This example shows you how to create, visualize, and analyze a coupled line filter.
Create a coupled line filter with default properties.
filter = filterCoupledLine
filter = filterCoupledLine with properties: FilterOrder: 3 PortLineLength: 0.0279 PortLineWidth: 0.0051 CoupledLineLength: [0.0279 0.0279 0.0279 0.0279] CoupledLineWidth: [0.0036 0.0049 0.0049 0.0036] CoupledLineSpacing: [1.8270e-04 0.0019 0.0019 1.8270e-04] Height: 0.0016 GroundPlaneWidth: 0.0551 Substrate: [1×1 dielectric] Conductor: [1×1 metal]
View the filter.
show(filter)
Plot the charge distribution at 5 GHz.
charge(filter,5e9)
Plot the current distribution at 5 GHz.
figure current(filter,5e9)
Calculate and plot the s-parameters.
spar = sparameters(filter,linspace(1.5e9,2.5e9,101)); figure,rfplot(spar)
