What HYTEM does

HYTEM is a French industrial company founded in 1994 that designs and manufactures RF and microwave components, interconnect solutions, and integrated systems from a single ISO 9001-certified facility in Villeconin, south of Paris. Its portfolio spans standard and specialty coaxial cables (including miniature, high-density multipoint, thermal vacuum, and military-grade variants), coaxial connectors and adapters covering frequencies up to 110 GHz, and a full RF components line of attenuators, couplers, switches, isolators, filters, amplifiers, antennas, and waveguide devices. On top of the component catalog, HYTEM delivers integrated RF systems such as attenuator banks, switching matrices, programmable and manual variable attenuators, phase shifters, GPS/GNSS distribution units, and customer-specific integrations.

The company serves enterprise customers across telecommunications (Nokia, Orange, Proximus), defense and military (Thales, Thales Alenia Space, Naval Group, MBDA), aerospace, industrial (Siemens, Safran), medical, railway, EMC testing, and research laboratories. It operates a direct field-sales model with dedicated technical sales engineers covering northern and southern France, complemented by an inside-sales function, and additionally serves as the official French distributor of Bird Technologies' RF test and measurement equipment, including the GenHawk GH-60 portable vector signal generator. Revenue is generated through one-time hardware sales and custom system integration contracts on a quote-based pricing model, with no subscription or recurring software line.

HYTEM is a privately held SAS (share capital €100,800), managed since inception by Managing Director Alain Désiré, with no disclosed institutional investors, parent company, subsidiaries, or funding rounds. The company holds ISO 9001 certification since 2001, the French Fab label since 2022, and an EcoVadis Bronze Medal awarded in 2026, and participates regularly in European RF/microwave trade shows (EuMW, EMC Europe, JNM, AOC Europe). Its stated scale metrics are 8,000+ product references and 1,350+ customers served, with a disclosed headcount range of 11–50 employees.
