Self-biased Circulators for Size Weight and Power Restricted Applications
Metamagnetics Inc., Massachusetts, United States
In order to address the urgent need for reduced T/R module size, cost, and weight as well as improve system robustness. Metamagnetics has developed an innovative circulator technology based on self-biased hexaferrite materials. These devices do not require external biasing magnets reducing device complexity, device weight and volume by 90%.
Primary Application Area: Electronics, Sensors & Communications
Technology Development Status: Prototype
Technology Readiness Level: TRL 5

GOVT/EXTERNAL FUNDING SOURCES
Government Funding/Support to Date: Metamagnetics’ initial technology development efforts were supported under a Ph1 NAVY SBIR contract (2011) N00024-11-C-4184 (150k). The success of the initial effort in demonstrating low-loss substrate materials prompted a follow-on Ph2 effort (2012, 750k). This effort was successful in raising the technology to a TRL of 5. Metamagnetics is currently in the final option phase of this Ph2 contract and is working closely with program sponsors at NAVSEA to locate a Ph3 transition. Alongside this effort, Metamagnetics won a Ph1 SBIR from NASA in 2013 (125k) to develop this technology for space-based applications. Over the course of this effort Metamagnetics developed ~100 prototype devices at a TRL of 5. Program managers at JPL were impressed with the technology and its potential to reduce the weight of current and next-generation satellite systems. Metamagnetics has applied for Ph2 funding from NASA (2014) with a targeted goal of TRL 6 through direct iteration of this technology with a prime partner into a planned NASA system. The expected start date for this effort is Q2 2014. Finally, Metamagnetics has been awarded a Massachusetts State Grant (100k) to aid in the commercialization of this technology. This money has been earmarked for activities related to business development not funded through the SBIR process. Metamagnetics plans to apply for a follow-on grant from the state in 2014. Metamagnetics has not received any outside funding for this effort and as such all equity is still owned by the company.
