Radiation Tolerant RF System for Spaceborne Communication

Background: Integrated circuits are essential for spaceborne communication but face significant challenges due to radiation from energetic particles in space. Atomically thin materials like MoS2 offer potential advantages due to their ability to withstand radiation-induced damage.

Method: We developed a radiation-tolerant RF system operating in the 12-18 GHz frequency range, utilizing a monolayer 2D MoS2 atomic-layer transistor fabricated on a 4-inch wafer. The system was tested in a low Earth orbit approximately 517 km above the Earth, with integrated transmitters and receivers for satellite communication.

Results: After 9 months of operation in orbit, the system demonstrated a bit error rate (BER) of less than 10−8, showcasing its radiation tolerance and long-term stability. Additionally, predictions indicate a potential lifespan of approximately 271 years, even in a geosynchronous orbit subjected to intense radiation.

Conclusion: This study supports the feasibility of using monolayer 2D MoS2 materials in the development of robust spaceborne communication systems. The findings suggest a significant advancement in radiation-tolerant electronics, with implications for improved satellite communications. Future research should focus on validating these predictions over longer durations and under various radiation environments.
