Notes/Equations
- All ports are assumed to have the same VSWR.
- Isolation is assumed to be constant across all frequency bands.
- Up to three frequency breakpoints can be used to define four bands, with different losses and VSWR for each frequency band. If frequencies are not specified, this model is frequency independent and uses Loss1 and VSWR1 only.
