Metamagnetics Unveils Revolutionary Self-Biased Circulators for Defense Applications

Metamagnetics Introduces Cutting-Edge Self-Biased Circulators

On May 8, 2025, Metamagnetics Inc., a promising startup in the defensetech sector, announced the launch of its groundbreaking Self-Biased Circulators. These advanced RF (Radio Frequency) components are engineered specifically for military and aerospace applications, demonstrating exceptional performance in a remarkably compact size without the need for rare-earth magnets.

Metamagnetics' new product line was developed in response to increasing concerns over the reliance on rare-earth materials, predominantly sourced from China, which poses significant vulnerabilities to U.S. national security and economic stability. By eliminating the dependency on these magnets, Metamagnetics addresses critical supply chain security concerns while maintaining high reliability and operational performance.

The Self-Biased Circulators excel in various demanding conditions, boasting a footprint of merely 0.100-inch x 0.110-inch x 0.010-inch. Impressively, they are over 90% lighter and smaller in volume when compared to conventional components that depend on rare-earth bias magnets. These circulators can withstand extreme environments, enduring shock and vibrations exceeding 50,000 g-forces, all while ensuring consistent performance, a feat that sets them apart from existing technologies.

Vince Harris, the Founder and CEO of Metamagnetics, expressed pride in the introduction of the Self-Biased Circulators, emphasizing their alignment with the needs of Department of Defense planners and military personnel. He stated, "Our Self-Biased Circulator's performance, size, and weight underscore a unique design that eliminates the necessity for rare-earth bias magnets, marking a significant advancement in RF technology. Metamagnetics continues to pioneer transformative solutions aimed at overcoming substantial challenges in securing communications, intelligence gathering, and reconnaissance across contested domains."

These circulators are engineered to be easily integrated into various defense systems, representing the industry's only solution that combines a compact form factor, enhanced performance, and secure supply chain advantages. Designed specifically to support advanced military RF systems, the Self-Biased Circulators will play a crucial role in ensuring the effectiveness and efficiency of critical defense operations.
