Nexxim Simulator > Open Stub, Physical Length
Netlist FormatAn instance of a grounded coplanar waveguide open stub, physical length has the following netlist syntax: Axxx n1 [W=val] [G=val]
[P=val] [GAP=val] n1 is the name of the node attached to the open stub. The entry COMPONENT=gcpw_open_stub_physical identifies the element as a grounded coplanar waveguide open stub, physical length. The SUBSTRATE=substrate_name is the grounded coplanar waveguide substrate model name selected for the design (see Selecting a Grounded Coplanar Waveguide Substrate for details).
Netlist ExampleA5 Port1 W=0.75e-3 G=1.1e-3 P=2.5e-3 GAP=1.75e-3 COMPONENT=gcpw_open_stub_physical SUBSTRATE=GCPW1 where GCPW1, the selected layout technology or substrate type, has a definition such as: .SUB GCPW1 GCPW( Notes1. The substrate thickness must be larger than (W + 2*G), so that the effect of the lower ground plane is negligible. 2. The physical model using physical length includes the open end length correction. 3. The GCPWOST model is equivalent to a transmission line followed by an open model. This is also true in the case of negative length specifications which are used for de-embedding. HFSS视频教程 ADS视频教程 CST视频教程 Ansoft Designer 中文教程 |
