With increasing power demands for satellite RF systems, preventing RF breakdown in components is essential to ensure proper satellite operation. The Aerospace Corporation is leading research into plasma and multipactor breakdown through basic research and helping contractors develop better hardware and testing. Their goal is to decrease risk through improved understanding of RF breakdown from component design through on-orbit operation. Aerospace has characterized various breakdown signatures and developed new diagnostics for improved multipactor detection sensitivity to help prevent catastrophic failures. Their multidisciplinary team contributes to mitigation of RF breakdown through diverse expertise in areas like RF engineering, plasma physics, materials science, and systems engineering.
