Switchable L-Band Auto-tune Filter Module

Assured communications is a critical asset for Navy warfighters during operations in congested and contested electromagnetic (EM) environments. They face SNR degradation or even hardware damage from both hostile and friendly high-power EM emitters that can cause electromagnetic interference (EMI), such as a co-located emitters, intentional jamming, and other EM environmental scenarios. Metamagnetics has developed a passive, automatically reconfiguring, RF signal conditioning component technology called the Auto-tune Filter (AtF). AtF technology is unlike any existing filtering and/or limiting technology and is exceptionally effective in enabling modern wideband RF receivers to maintain high sensitivity when subjected to a wide range of electromagnetic interference types. AtF technology is well-suited to mitigate co-site interference and high-power microwave threats such as electronic warfare platforms and stations. Its high-power handling ability makes it particularly useful for protecting receivers from high power emitters (i.e. radar stations, electronic warfare (EW) platforms, jamming pods, etc.), and acting as a æsmartÆ limiter for providing frequency selective limiting of high-power electromagnetic (EM) threats. In this effort, Metamagnetics will develop a module tailored to protect Navy communications equipment from a wide range of EMI conditions.
