Researchers at Novgorod State University are developing a compact power splitter for radio signals that utilizes acoustic waves instead of traditional inductors and capacitors. The device is designed to reduce energy consumption and improve signal distribution accuracy while eliminating the need for imported components.
The splitter consists of a composite structure made from lead zirconate titanate piezoelectric ceramic and an amorphous magnetic alloy. When a radio signal is applied, the alloy undergoes mechanical deformation, creating elastic standing waves within the composite that are subsequently converted into electrical voltage.
The power distribution between output ports is managed by adjusting the length of metal contacts that capture different segments of the wave. This mechanism allows for precise signal division and is expected to minimize device size, energy loss, and heat generation during operation.
The project team includes postgraduate student Gleb Koifman, supervisor Dmitry Filippov, and researcher Stanislav Sapelnikov. Potential applications for this technology include telecommunications equipment, geological exploration, and the oil and gas industry.
