Electronic components face a host of challenges while in space, from extreme temperature variation to space radiations. These harsh conditions mean that any Commercial Off-the-Shelf (COTS) component cannot be used for space missions. The electronic components used in making satellites must be able to withstand a wide range of environmental challenges – from the complexities of being launched from Earth to the extremely harsh environment of outer space. everything RF has compiled a list of 10 trending space-qualified RF components. Visit the new SPACE HUB on everything RF to keep up to date with the latest on space-qualified components.
