everything RF visited the Metamagnetics booth (#24088) at IMS 2026, where the company showcased a portfolio of RF solutions designed for assured communications and electronic warfare applications. The display highlighted technologies designed to improve communication resilience and spectrum survivability in increasingly congested electromagnetic conditions.
At the booth, Reena Dahle, Senior Director of Engineering at Metamag, presented its core technology areas: rare-earth-free self-biased circulators and isolators, AutoTune Filters (ATFs), and signal conditioning modules, each addressing wideband signal protection and interference mitigation in high-power, co-site environments.
The company’s rare-earth-free self-biased circulators and isolators eliminate the need for permanent magnets while maintaining RF performance. Operating across high-frequency ranges from approximately 26 GHz to 110 GHz, these devices offer significant reductions in size and weight compared to conventional designs and are built for deployment in radar, communications, and electronic warfare systems operating in harsh conditions.
Metamagnetics also showcased its AutoTune Filter technology, a passive, adaptive solution that functions as a frequency-selective limiter. ATFs automatically generate rejection notches at frequencies where signals exceed a defined power threshold, while allowing lower-power signals to pass with low insertion loss.
They operate in real time, adjusting to changing interference, with response times on the order of tens to hundreds of nanoseconds and recovery times below ~500 ns in typical designs. High-power handling capability includes up to about +40 dBm CW input and peak pulsed power on the order of 1 kW (device-dependent). The ATF portfolio covers frequencies from ~0.8 GHz (sub-GHz bands) up to approximately 18 GHz, with multiple variants offering insertion loss around 2–3 dB, power thresholds ranging roughly from −23 dBm to +15 dBm, and different bandwidth and packaging options.
In addition, the company presented its signal conditioning modules, which leverage ATF technology to provide adaptive, wideband signal conditioning. These modules operate from DC to 18 GHz and support power handling of up to 10 W CW and 1 kW pulsed. Designed to protect receivers and downstream RF components, they help improve system dynamic range and mitigate high-power interference while preserving signals of interest.
Metamagnetics’ demonstration at IMS 2026 focused on RF technologies that enhance electronic warfare survivability and support reliable operation in contested RF environments, combining autotune filtering, compact circulator designs, and wideband signal conditioning for defense and aerospace applications.
