Objectives
The Project Objectives were to develop bandpass filters within input multiplexers operating in Ka-band uplink (30 GHz). The need for this technology exists on the market and is currently met with filters in waveguide technology. The technology of this project aims at replacing waveguide technology by dielectric technology, resulting in a hardware offering similar electrical performance but with the advantage of smaller mass and footprint. Also the technology will offer more standardized layout, thus facilitating design flow and integration on the satellite panel.
Challenges
This key success factor was the correlation of full wave simulation to the test data from suitable designed hardware. Three iterations of this development cycle were performed: First cycle was Pre-Breadboard hardware for concept selection. Second cycle was Breadboard hardware to target actual requirements. The final development cycle generated the EM hardware which was tested within an agreed test campaign
System Architecture
Layout of input multiplexer assembly benefits from the standardized mechanical filter design, allowing for assembly mechanical design in repeatable pattern.
Plan
The project was structured in two phases, each phase consisting of several Workpackages.
Phase one was dedicated to the development of the Filter Concept. Key Workpackages were dealing with material selection, selection of filter design concept and verification of both choices by breadboard. Phase two was dedicated to EM Manufacturing and test and analysis of the results.
Current Status
The project has been completed. The development from Feasibility Study to Demo was covered by the project.
