Custom development and manufacturing of antennas, RF components, circuits and systems for industrial applications.
Sevskiy GmbH
Munich (headquarters and RF laboratory)New on Amplifa
One partner for the entire RF path
Sevskiy GmbH, headquartered in Munich with an RF laboratory, develops and supplies antennas, RF components, circuits and systems for industrial applications. Development work began in 2009 as an engineering office; today the offering includes complete new developments, optimization of existing products and adaptation of series products. Antenna, filter, amplifier, cable, printed circuit board and RF chip are considered as a connected signal path. Capabilities include electromagnetic field simulation (HFSS, CST), circuit design, impedance-controlled PCB layout, prototype construction and measurement-based validation up to 26.5 GHz, including noise figure, power and intermodulation measurements. More than 2,700 optimized layouts demonstrate experience with matching, grounding, RF transitions and interference coupling. The company's own product range of around 140 variants includes embedded PCB and patch antennas, RF filters, low-noise amplifiers (LNA) and micro-coax cable assemblies; mass production is carried out by qualified partners, and the company's own products are distributed via the DigiKey shop.
