OneFiltr: Smaller, Smarter, and DC Power-Free
OneFiltr: Smaller, Smarter, and DC Power-Free
Embedded Files
OneFiltr breaks through traditional limitations with two core innovations: eliminating DC power consumption and reducing size and weight by more than 20x. Our advanced Yttrium Iron Garnet (YIG) manufacturing and transducer design also replace costly YIG spheres—cutting costs and boosting scalability without sacrificing RF performance.
Traditional YIG filters face size and power consumption challenge.
Traditional YIG filters face size and power consumption challenge.
Yttrium Iron Garnet (YIG)-based tunable filters are known for their wide tuning range, high quality factor, and excellent linearity. But their reliance on bulky electromagnets and constant multi-watt power draw limits their practicality and scalability.
Innovation#1: Zero Static Power Magnetic Bias Circuit
Commercial YIG Tunable Filter
Electromagnets provide magnetic field, requiring constant power and large space.

A small coil current pulse shifts AlNiCo’s magnetization, altering the magnetic field, which remains even without power.
Innovation#2: Microfabricated YIG cavity
Commercial YIG Tunable Filter
Each YIG sphere costs hundreds of dollars, requiring several spheres per filter.
