Kaelus

What Kaelus does

Kaelus is a Swedish-headquartered RF technology company specializing in antenna systems, RF conditioning products, and test & measurement instruments for the global wireless telecommunications industry. Founded in 1981 as Microdata Stockholm Innovation AB and rebranded to Kaelus in 2021, the company traces its lineage through LGP Telecom, LGP Allgon, Powerwave Technologies, and Filtronic — consolidating decades of Swedish RF engineering heritage. Its product portfolio spans beam-through antennas for mMIMO, base station and small cell antennas, Galtronics-branded stadium/multibeam antennas, tower mounted amplifiers (TMA), multi-band combiners, interference filters (including the remotely tunable KA-6008 for C-band), dual-band GNSS synchronization antennas, and a test & measurement suite featuring iPA/iXA portable PIM analyzers, iBA bench PIM testers, iVA/iWA cable and antenna analyzers, PIM Finder external detection solutions, the ACE-1000A field self-calibration system, and the RTF (Range-to-Fault) module — all unified under the Kaelus Unify software platform.

Kaelus operates a B2B enterprise sales model, selling directly to tier-1 wireless carriers, telecom OEMs, defence organizations, and broadcasters across North America, Europe, Asia-Pacific, and Latin America. Pricing is quote-based with no public disclosure, and revenue is generated through hardware product sales supplemented by calibration, repair, training, and certification services. The company holds ISO 9001, ISO 14001, and ISO 45001 certifications across its Sweden, Finland, China, and Australia operations.

On May 29, 2026, Kaelus was acquired by Baylin Technologies Inc. (TSX: BYL) for approximately SEK 282 million (C$42 million) in cash and shares, uniting it with Baylin's wholly-owned subsidiary Galtronics to form a comprehensive end-to-end RF solutions portfolio. Pro-forma 2026 combined revenue across Baylin, Kaelus, and Galtronics is projected at approximately C$130 million with adjusted EBITDA of roughly C$14 million. Kaelus maintains its brand identity as a wholly-owned subsidiary within the Baylin group, with regional sales and service offices in Sweden (HQ), the United States, Australia, China, and Finland serving a global customer base.
