Metamagnetics Inc., a leader in adaptive RF technologies, has developed a Surface-Mount Auto-Tune Filter (AtF®-SM). Auto-tune Filters™ (AtFs) are a better alternative to limiters and filters. They provide a broadband, fast-response, simple solution that protects receivers from electromagnetic interference (EMI) and ensures that signals-of-interest are detected. These devices have a power threshold level which no one signal can exceed. If one or more signals exceeds the threshold, the Auto-tune Filter™ automatically limits it by attenuating the signal.
Building on the company's deployed AtF® technology success, the Surface-Mount Auto-Tune Filter (AtF®-SM) delivers PCB-level integration across wide frequency ranges. It autonomously notches unwanted high-power signals to protect sensitive receiver front ends while preserving the reception of signals of interest (SOI) - all without power, external control, or calibration.
"The shift toward smaller, networked, multi-RF autonomous platforms demands scalable, embedded RF resilience," said Vince Harris, Founder and CEO of Metamagnetics Inc. "Our new surface-mount AtF® allows customers to design and deploy next-generation radios and ISR payloads with built-in co-site and jamming immunity - no manual tuning, no software, no compromises."
Key Features of AtF®-SM:
- Surface-Mount Design: Compatible with automated PCB assembly for seamless integration into compact, mission-critical RF systems.
- Auto-Adaptive Filtering:Real-time response to co-site interference and jammers, ensuring uninterrupted reception of desired signals in contested environments.
- Performance and Dimensions: Passive operation across UHF to S-band, with a compact 10 mm × 10 mm footprint for the reflective line of devices.
- NDAA-Compliant/U.S.-Made: Designed and manufactured domestically with a secure and traceable U.S. supply chain.
- Ideal Applications: Tactical radios, SIGINT front ends, telemetry receivers, EW payloads, and high-density unmanned platforms.
