Metamagnetics Introduces Innovative Auto-Tune Filter for RF Resilience

Metamagnetics Unveils Cutting-Edge Surface-Mount Auto-Tune Filter

MARLBOROUGH, Mass., November 18, 2025 – Metamagnetics Inc., a frontrunner in adaptive RF technologies, has announced a groundbreaking addition to its product lineup - the Surface-Mount Auto-Tune Filter (AtF®-SM). This innovative solution stands out as the first fully self-tuning, surface-mount RF interference mitigation and anti-jamming technology, specifically designed for use in radios, receivers, radars, and electronic warfare systems, especially those operating in densely populated and contested electromagnetic scenarios.

Following the success of their existing AtF® technology deployed in various military applications, the AtF®-SM enhances signal integrity by delivering printed circuit board (PCB)-level integration across a broad frequency range. One of its standout features is its ability to autonomously notches out unwanted high-power signals, safeguarding sensitive receiver front ends while continuing to maintain the reception of critical signals of interest (SOI). Importantly, this operation requires no external power, control, or calibration, making it highly efficient.

As Vince Harris, the Founder and CEO of Metamagnetics Inc., stated, “The shift toward smaller, networked, multi-RF autonomous platforms demands scalable, embedded RF resilience. Our new surface-mount AtF® enables customers to design and deploy next-generation radios and ISR payloads, equipped with built-in co-site and jamming immunity.” This means that users can expect seamless integration in mission-critical systems without compromising performance.

Key Features of AtF®-SM

1. Surface-Mount Design: This filter is compatible with automated PCB assembly, enabling straightforward integration into compact systems critical for mission success.
2. Auto-Adaptive Filtering: It boasts real-time responsiveness to localized interference and jammers, ensuring that desired signals remain uninterrupted even in competitive environments.
3. Compact Form Factor: Measuring only 10 mm × 10 mm, it allows for fitting in space-restricted applications easily while working efficiently across UHF to S-band frequencies.
4. NDAA-Compliant/U.S.-Made: Staying true to its commitment to national security, the AtF®-SM is designed and manufactured domestically, ensuring a secure and traceable supply chain.

Ideal Applications

The Surface-Mount Auto-Tune Filter is well-suited for various applications, including tactical radios, SIGINT (signals intelligence) front ends, telemetry receivers, electronic warfare payloads, and high-density unmanned platforms. Its versatility makes it an indispensable tool in modern communication and surveillance systems.
