In the INFERSAT project (Integration ofFERrite Materials for Components in SATellite Communication), components (especially circulators) are to be developed for high-frequency applications. The aim is to improve flexible communication satellites with respect to efficiency (ratio of payload to function, costs) and operating parameters (bandwidth, reconfigurability, etc.) in the long run. The processing of the RF components (ferrite integration into LTCC technology) is the responsibility of the Electronics Technology Department at Ilmenau Technical University. The existing technology know-how is applied and the research results regarding ferrite materials from the iKERSATEC project are extended.
With the LTCC technology it is possible to develop highly integrated multilayer modules. The ferrites can therefore be integrated into the technology in a very compact way. The multilayer process eliminates hybrid integration steps and connection techniques such as bonding, bonding or soldering. This avoids high integration costs and possible air gaps at connection points.
Various ferrite materials (hard and soft ferrites) are to be researched and embedded in LTCC technology. Frequencies in the range 27.5 to 31 GHz for soft ferrites and 37.5 to 42.5 GHz for hard ferrites are targeted.
The following points should be taken into account during implementation: Volume/weight and cost reduction Increase of the operating frequency and thus the available bandwidth for communication applications Optimization of thermal management by embedding the components in the ceramic circuit carrier Improvement of reliability (mechanical, EMC) Modularization for optimal reusability Radiation resistance and vacuum suitability
At the end of the project, the developed technology is to be transferred into a process ready for series production.
The consortium of SMEs and research institutions pursues the strategic goal of strengthening the competencies in the field of subsystem and component development and technology in Germany as a business location. INFERSAT lays the foundation for the economic exploitation of these components for space applications.
