ALTER is performing gamma and proton radiation at various PICs. The satellite market is experiencing a paradigm shift with the photonics penetration in every part of the satellite payload. Although some advances have been done with the introduction of optical interconnects in a commercial digital processor of a satellite payload

The most relevant result of this work is that all tested samples passed satisfactory the test without relevant changes in the measured parameters, with the exception of one of the WG-EO switches which had a catastrophic failure, as it will be commented later. The pass/non-pass criteria were defined comparing the results of the electro-optical characterization after each test with the corresponding results for each parameter prior to the tests, taking into account the measurement uncertainty.

New automotive-grade product series to its high current shielded power inductor line. The new series offers a metal alloy powder core in shielded construction for high rated current, low radiation, low buzz noise and wide operating temperature range. The new Model SRP7028AA, SRP7050AA and SRP1038AA series are designed to meet today’s high current density and high temperature requirements for power management and EMI filtering in DC-DC converters and power supplies in consumer, industrial, and telecom electronics applications.

TID effects imply that one incident irradiation causes the ionizing of matter and it appears charge in places where it should not. TNID effects are motivated by the displacement of the atoms of the crystalline lattice from their balance sites.

The radiation analysis is an essential document for the revision and approval of the components used within space equipment. This document includes in a single place all the information (data, assumptions and methods) and the results obtained when analyzing the radiation effects in the components used.
