Metamagnetics Inc. has introduced a new line of ultra-compact RF and millimeter-wave circulators and isolators that eliminate the need for rare-earth magnets—materials typically sourced from China and a growing concern for U.S. national security. These new "Self-Biased Circulators" offer high-performance signal routing in advanced military systems without relying on foreign supply chains.
Built entirely with a U.S.-based supply chain, the devices are over 90% smaller and lighter than traditional models, with a footprint no larger than a grain of rice. Despite their size, they’re engineered to endure extreme environments—surviving shock levels over 50,000 g-forces—making them ideal for aerospace and defense applications, particularly in high-frequency Ka-band systems and beyond.
"[...] Metamagnetics continues to bring to market transformational RF solutions that address the greatest challenges in assured communications and broader intelligence, surveillance and reconnaissance missions across contested domains," said Vince Harris, Metamagnetics' Founder and CEO.
