Linear Receivers for a Congested and Contested Electro Magnetic Domain

Important results from the project

Aim of the project was to develop linear receivers for lightweight construction by studying new semiconductor materials with specifically developed graded epitaxial layers for extended linearity. The project has driven research in the area. Chalmers has carried out the analysis and manufacture of transistors and Saab has evaluated the electrical properties for microwave construction. The measurements made within the project show markedly increased linearity in the new transistors compared to traditional ones. This contributes to more robust receivers that are harder to jam.

Expected long term effects

** Denna text är maskinöversatt ** The work carried out within the framework of the project strengthens the aviation industry by improving the conditions for more robust microwave modules in semiconductor materials, which are of great importance for compact and lightweight systems found, among other things, in fighter aircraft and UAVs. In addition, the project contributes to maintaining Swedish excellence in the field and strengthen cooperation between industry and university colleges.

Approach and implementation

** Denna text är maskinöversatt ** The project has been carried out in collaboration between industry and university college. Chalmers has assisted with the analysis of semiconductor materials and the manufacture of transistors. Saab has been responsible for the characterization and modeling of transistors. Saab has also been responsible for project administration, including requirements and project management. In order to follow up the progress of the project, quarterly follow-up meetings have been held.
