Periodic Reporting for period 3 - SELECTOR (Smt compatible ELECTroMechanical relay for cOmpact redundancy Ring)
Reporting period: 2021-12-01 to 2022-09-30
Regarding the technical part, we reached a TRL 7. First the specifications have been established. Next the research & developpement task has allowed to obtain innovative features of the switch. Indeed the hermeticity of the switch is IP67, the RF performances are satisfactory until 32 GHz (operating frequency: DC-32 GHz, isolation: DC-22GHz: -50 dB max/ 22 GHz-32GHz: -50 dB max, shielding efficienty: DC-22GHz: -40dBi / 22 GHz-32GHz: -40dBi) and the switch is compliant with the space environment and with the Thales requirements. The design of the switch is fixed and Radiall has started the industrialization with the developpement of several tools, tests bench etc...
Thales has also developped the redundancy ring and finished the qualification. CSEM has realized the MEMR reliability assessment methodology and test plan definition.
The advisory board has been involved at different steps of the project to define the specifications and to established qualification test plan of the switch.
To finish the consortium made the promotion of the selector project by different channels:
A dedicated graphic chart has been put in place for the different support of communication. The selector website is available and present the differents steps of the project.
However the communication in conference has been impacted by the covid crisis. Several conference have been canceled but at the end of the project the consortium did an additional effort to catch up. the consortium has participated to EMW conference, SPCD conference and ESREF conference. Regarding the publications, the consortium has submitted several papers, one in the CSEM Scientific and Technical journal in 2021 and another one in microelectronics reliability journal in 2022
The economic impact for Radiall should lead to the hiring of 4 people and about 200 people for Thales.
