Lumped Ports in the RF Module
Not all models can use lumped ports due to the polarization of the fields and how sources are specified. For the physics interfaces and study types that support the lumped port, the Lumped Port is available as a boundary feature. See
Lumped Port
for instructions to set up this feature.
Lumped Port Variables
Each lumped port generates variables that are accessible to the user. Apart from the S-parameter, a lumped port condition also generates the following variables.
Name
Description
Vport
Extracted port voltage
Iport
Port current
Zport
Port impedance
For example, a lumped port with port number
1
, defined in the first geometry, for the Electromagnetic Waves interface with the tag
emw
, defines the port impedance variable
emw.Zport_1
.
