About Silicon Audio RF Circulator, LLC
Silicon Audio RF Circulator, LLC, doing business as Silicon Audio, LLC, is a for-profit limited liability company based in Austin, Texas, specializing in advanced research and development of radio frequency (RF) and optical technologies for the Department of Defense. The company focuses on cutting-edge technological innovations in areas such as electro-optic modulators, antenna technologies, and specialized circuitry. As a small business registered in SAM.gov since 2015, Silicon Audio has positioned itself as an innovative technology partner for federal agencies, particularly in defense-related research and development initiatives.
The company has secured multiple Small Business Technology Transfer (STTR) Phase I and Phase II contracts with the Department of Defense, specifically through the Washington Headquarters Service and the Office of the Secretary of Defense. These contracts are consistently set aside for total small business participation and focus on advanced technological developments. The contract awards include research on dispersion engineered passive matching loads for extending antenna bandwidth, ultra-compact wideband electro-optic modulators using ferroelectric materials, and magnet-free quasi-electrostatic circulators and topological insulators based on temporal modulation. The total value of these defense-related research contracts exceeds $3.9 million, with completion dates ranging from May 2023 to July 2027.
Silicon Audio has also received a federal grant from the National Institute on Deafness and Other Communication Disorders (NIDCD) valued at $292,694.00. This project grant, which runs from August 1, 2025 to July 31, 2026, focuses on developing high signal-to-noise ratio miniature microphones for hearing assistive devices. The research aims to leverage advances in single-crystal lithium niobate (LN) and wafer processing to create bimorph LN diaphragms that can achieve a significant improvement in signal-to-noise ratio for hearing aid microelectromechanical system (MEMS) microphones. This grant demonstrates the company's ability to apply its advanced technological expertise to healthcare-related research and innovation.
