The Silicon Carbide power diodes were specifically designed for protection of solar cells arrays in solar panels mounted in satellites and space exploration modules. The first batches of devices are currently used for two European Space Agency missions, BepiColombo and Solar Orbiter.
The paper describes the activities and results of an ESA-funded project concerned with the assessment of optical amplifier technologies and products for applications in fiber optic subsystems of future satellite payloads. Onboard applications are briefly introduced, together with associated system-level requirements. Optical amplifier technologies, research achievements and products are reviewed.
It is common knowledge that leads time is often a critical aspect of Procurement of EEE parts for Space Applications. Some specific family types usually suffer from having long lead times (more than 1 year on some occasions), which makes them a major driver on any procurement. One of the most affected families are Space Qualified Panel C Mounted EMI filters.
For passive devices testing, we have equipment which permits the characterization of the electrical behavior of resistors, capacitors, coils, etc., in a wide range of test conditions and in accordance with their applicable specifications: Measurement and testing of high power devices, Dielectric withstanding, voltage up to 12 KV Characterization on LCR devices up to 3 GHz
The new CERN High energy AcceleRator Mixed Field facility (CHARM) allows to test several single components, as well as more complex devices, at different locations, characterized by particle spectra representative of the high- and low-altitude atmospheric, particle accelerator and ground environments.
The Total Ionizing Dose (TID) radiation test on EEE parts involves a number of variables and processes which must be kept under control to ensure correct test execution and compliance with the used test method. From the test plan definition to the test report issue, the proper methodology needs to be put in place.
