The Self-Biased Circulators from Metamagnetics are unique Ka-Band circulators that do not use magnetic materials. The circulators use an innovative material that is created by aligning magnetic grains and then processing them at high temperatures to create an ultra-dense compact material that is free of defects and voids. They have no magnets which allow more space and achieve a 90% reduction in size and weight over traditional microstrip permanent magnet circulators.
The Self-Biased Circulators enable developers to produce high power, broadband radar systems that achieve their goals for size, weight, power, and cost reductions (SWaP-C), while also enabling a variety of novel system design and surface mount installation approaches. They can be mounted to a housing or printed circuit board using conductive epoxy or solder. These circulators are ideal for use in a wide variety of commercial and military applications, including radar, wireless, and satellite communications. Examples of these applications include military target tracking, automotive intelligent cruise control, and collision avoidance, 5G high capacity, gigabit-speed wireless and Wi-Fi systems, and satellite-based surface water and ocean topography.
These circulators can survive over 50,000 Gs enabling new communication platforms and can be used under harsh conditions, such as missile launches.
