RF Microwave

What RF Microwave does

RF Microwave is the e-commerce trading name of Welco Srl, an Italian private limited company headquartered in Cesano Maderno (Monza-Brianza) with a registered office in Senago. Founded in 2021 as the legal successor to R.F. Elettronica (established 1992 by Rota Franco), the company distributes RF, microwave, and millimeter-wave electronic components — coaxial connectors, adapters, cables, attenuators, ferrites, toroids, diodes, transistors, capacitors, filters, and connectorized RF modules — serving telecommunications, defense and aerospace, test and measurement, broadcast, research and development, and OEM/manufacturing customers globally. Its catalog of more than 6,000 products is available for immediate delivery through a multilingual self-serve storefront (English, Italian, German, French, Spanish) accepting 20+ currencies, supported by an online Coaxial Cable Configurator and pre/post-sales technical consultation by phone and email. The business carries its own QAXIAL coaxial brand (PTFE-insulated exclusively) and distributes tier-one third-party brands including Huber+Suhner, Radiall, RFS, Rogers Corp, Spinner, Tronser (exclusive for Italy), Farran, Micrometals, MagWave, Exxelia, Kyocera AVX, Suntan, and Vishay.

Welco Srl supplements distribution with in-house custom RF coaxial cable assembly at its Cesano Maderno facility. Configured online and produced to specification, each cable undergoes 100% electrical testing with S-parameter test reports (return loss and insertion loss) before shipment, under an ISO 9001:2015 certified quality management system. Revenue is generated primarily through one-time unit sales of catalog components and custom-assembled cables, with no disclosed subscription, licensing, or recurring contract layer. Pricing is largely pay-as-you-go with quote-based enterprise pricing, quantity discounts on selected SKUs, low minimum order thresholds, and free domestic shipping within Italy and San Marino up to 10 kg. The company also operates as a registered supplier on Italy's MePA public-administration procurement platform. With 1-10 employees, no external funding, and no public listing, RF Microwave operates as a privately held, founder-successor-owned specialty distributor and light manufacturer focused on long-tail B2B/B2C demand for high-frequency passive and active RF components.

Recent moves11 records

Expansion highlights5 records

Broad incumbents

• Huber+Suhner: Huber+Suhner is one of RF Microwave's most prominent distributed brands and a global manufacturer of RF connectors, coaxial cables (SUCOPLATE, CELLFLEX, MULTIFLEX), and assemblies. As an integrated manufacturer with its own e-commerce channel, it competes upstream with RF Microwave on the same product families.
• Mouser Electronics: Mouser is a global e-commerce distributor with an extensive RF/microwave linecard and the operational scale (multi-language, multi-currency, fast global logistics) that dwarfs RF Microwave. It competes for the same engineer-buyer on commodity connectors, passives, and RF modules.
• Spinner: Spinner is a German manufacturer of precision RF connectors, adapters, and rotating joints that RF Microwave distributes. As a manufacturer with growing direct sales, Spinner competes upstream in the same coaxial and high-frequency connector categories RF Microwave aggregates.
• Radiall: Radiall is a French manufacturer of RF connectors, antennas, and interconnect solutions with a major presence in aerospace, defense, and telecom — exactly RF Microwave's target verticals. As both a key distributed brand and a competing supplier with its own direct channel, it is a relevant benchmark peer.
• Würth Elektronik: Würth Elektronik manufactures and distributes electronic and electromechanical components including a deep RF passives portfolio (inductors, ferrites, EMC components). Its catalog and channels overlap with several categories RF Microwave sells into, including ferrite cores and EMI/RFI suppression parts.
• Digi-Key Electronics: Digi-Key is a leading global electronic components distributor with broad RF component coverage and an industry-standard e-commerce platform. It overlaps with RF Microwave on virtually every category in the catalog and is a direct competitor for online design-in orders.

Direct peers

• Mini-Circuits: Mini-Circuits designs, manufactures, and distributes a broad portfolio of RF/microwave components (amplifiers, filters, mixers, splitters, attenuators) and operates a deep e-commerce catalog — closely comparable to RF Microwave's connectorized RF modules and passives assortment with worldwide shipping.
• Pasternack: Pasternack is a direct e-commerce specialist in RF, microwave, and millimeter-wave components, cables, connectors, adapters, and assemblies. Its product breadth, configurator-style custom cable offering, and engineer-focused site overlap closely with RF Microwave's core catalog and self-serve GTM.
• Richardson RFPD (Richardson Electronics): Richardson RFPD specializes in RF, microwave, and power conversion components distribution with design-in engineering support, mirroring RF Microwave's mix of distributed premium brands and value-added custom cable/assembly services for telecom and industrial customers.

Others

• Coilcraft: Coilcraft is a manufacturer of RF, power, and signal magnetics (inductors, transformers, chokes) that supplies into the same telecom, defense, and test & measurement segments RF Microwave serves. Comparable on catalog adjacency and customer base, although Coilcraft sells direct rather than via distribution.
