Sonnet Suites - Independent Port Reference Planes in V13
Independent Port Reference Planes
- Independent Edge Port reference planes now enable arbitrary line length de-embedding
- Works for Edge Ports, Co-Calibrated Port groups and SMD Component connections
- Calibration/Reference Plane settings have been moved to the Port Properties window

Edge (box wall) ports and internal Co-Calibrated ports can now be given independent reference planes. This is useful in situations where the the distance to a desired reference plane location differs between ports on the same edge, and the separation between their associated parallel lines leads to minimal cross-coupling. All reference plane settings have now been moved to the associated Port Properties window in the Sonnet Project Editor.
Ports that originate from a common edge may have either "shared" reference planes, or "independent" reference plane definitions. All ports within the shared reference plane group will have a common reference plane location, and cross-coupling between the transmission lines in the shared group is completely removed up to the shared reference plane.

MMIC distrbuted amplifer example with independent reference planes for the tranmission lines on each edge. The shared reference planes are shown with light arrows, the independent reference planes are shown with dark arrows.
