ESA EPPL Certified Products
UMS has built a strong heritage in space over nearly three decades, establishing itself as a trusted partner for the European space industry. Many of UMS's in-house III-V technologies, including GaAs and GaN, are approved for space use and listed in ESA's European Preferred Parts List (EPPL) - a major endorsement of their robustness and long-term reliability. As an authorized distributor for UMS, TMT provides technical data and procurement support for ESA EPPL certified products for space projects.
ESA EPPL Certification Process
ESA EPPL certification requires the component manufacturer to pass the ESCC (European Space Components Coordination) system audit, including: wafer-level process control and parameter statistical monitoring, 100% non-destructive testing at package level, radiation characteristics evaluation (total dose, single event effects), accelerated life testing and failure mode analysis. UMS products listed on the EPPL cover core categories including LNAs, PAs, and switches.
Space-Grade Reliability Assurance
Space environments impose extreme requirements on RF components: thermal cycling (-55°C to +125°C), total dose radiation (10 krad-100 krad), single event effect protection, low outgassing (TML < 1%, CVCM < 0.1%), and vacuum operational stability. UMS space-grade MMICs follow ESCC specifications at every stage from wafer fabrication to final delivery, ensuring zero-defect delivery.
UMS Space-Grade MMICs
Covering frequencies from L- to Q-band, UMS's space portfolio includes LNAs, power amplifiers, attenuators, detectors, mixers, down-converters, and variable gain amplifiers. With European foundry services and flexible packaging options, UMS supports established space programs and emerging commercial ventures alike.
