This element is OBSOLETE and is replaced by the Coplanar Waveguide Substrate Definition (CPW_SUB) element.
|Er||Relative dielectric constant||0|
|H||Substrate thickness||Length||0 um|
|T||Conductor thickness||Length||0 um|
|Rho||Metal bulk resistivity normalized to gold||1|
|Tand||Loss tangent of dielectric||0|
|HC||Cover height above substrate||Length||0 um|
Er. The permittivity of the substrate material relative to freespace εo = 8.854*10-12 F/M.
Tand. The dielectric loss tangent of the substrate material: (Tand = εr"/εr' with εr 1/2 εr'- jεr")
Rho. Rho is the volume resistivity of the conductors relative to gold: 2.44 x 10 -8 Ω*m)
Physical volume resistivity = Rho * 2.44 x 10-8 Ω*m.
H, HC, and T are cross-sectional dimensional variables given in default length units.
In a schematic that contains coplanar waveguide elements, at least one instance of this element must exist.
Name. Provides a unique identifier for each instance of CPWSUB. The coplanar waveguide elements have a CPWSUB parameter that indicates which CPWSUB element to use.
This element does not have an assigned layout cell. You can assign artwork cells to any element. See “Assigning Artwork Cells to Layout of Schematic Elements” for details.
