Teledyne e2v Semiconductors has shared new radiation test results for its EV10AS940, a 10?bit, 12.8 GSps, Ka?band?ready analog?to?digital converter designed for the most demanding space payloads and mission?critical systems.
The updated data gives space engineers more confidence when using the EV10AS940 in high?performance satellite communications payloads, synthetic aperture radar (SAR) systems, space electronic intelligence platforms and advanced space instruments, where speed, radiation tolerance and in?orbit reliability are non?negotiable.
As part of a broad single event effects (SEE) test campaign, multiple EV10AS940 devices were put through their paces at leading radiation facilities, including RADEF in Finland and the Texas A&M University Cyclotron Institute in the United States. The converters were exposed to heavy ions across a wide set of conditions, with linear energy transfer (LET) values reaching up to 94 MeV·cm²/mg.
Across every configuration tested, the team observed no single event latch?up (SEL), even at the highest LET levels, elevated temperatures and increased supply voltages. At the end of the campaign, all devices were still operating normally, with no loss of performance or functional degradation.
The EV10AS940 is built for high?bandwidth applications that need fast, reliable conversion in harsh radiation environments, such as satellite communications, radar, electronic intelligence and advanced space?borne instrumentation. These latest SEE results reinforce Teledyne e2v’s long track record in delivering high?reliability semiconductor technologies for space and defense programs.
Total ionizing dose (TID) characterization of the EV10AS940 has also been completed, confirming the device’s robustness for long?term operation in radiation?rich orbits. Additional qualification work is underway, with full test reports expected to be available by the end of 2026.
Leadership Comment
“These results give space system designers added confidence when selecting high-speed data converters for advanced payloads,” said Victoria Nasserddine, Product Marketing Manager at Teledyne e2v Semiconductors. “The EV10AS940 combines ultrahigh-speed performance with demonstrated radiation robustness, supporting applications where mission assurance and signal-chain performance are both critical.”
