FoU RMP HF. Development of S-parameter calibration in 2.4 mm cable interface

Important results from the project

The objective of the project has been to develop a calibration method for S-parameters in 2.4 mm cable interfaces with the associated measurement uncertainty. Both a traceable method and measurement uncertainty are produced so this is considered well fulfilled. The end goal is an approved CMC. External circumstances moved the original timetable for this, but the work is progressing within the framework of another assignment. A third goal around knowledge building around calibration on frequencies above 40 GHz has been completed. Even that goal can be considered fulfilled.

Expected long term effects

The project has resulted in a method to traceably calibrate S-parameters in 2.4 mm cable interfaces, with the associated measurement uncertainty. This is intended as a service aimed at Swedish industry, which is a results from the project. This service is now available. A second important results is the building of knowledge for measurement and calibration above 40 GHz. This knowledge is a necessary basis for any future project at even higher frequencies.

Approach and implementation

The project has been divided into several smaller work packages (WP). This has been proven efficient due to the fact that it has been possible to make smaller objectives that are easier to overview, without losing the overall objective. The original plan did also have a preliminary time schedule when the different WP’s were to be finished. In hindsight it was seen that some WP’s were rearranged in time in order not to lose any momentum in the project. The cause for this rearrangement was external over which the project had minimal influence.
