What Dr. Hubert does
Dr. Hubert GmbH is a privately held German manufacturer of precision power amplifiers and associated test instrumentation, founded in 1984 by Dr.-Ing. Manfred Hubert and headquartered in Bochum. Operating under the HUBERT brand (introduced 2007), the company designs and builds 4-quadrant linear amplifiers (Series A1110 and A1230), high-frequency RF amplifiers (Series A1020, up to 400 MHz), and a modular expandable amplifier system (A1500, scalable to 18 modules). In 2024 it broadened its portfolio with the FPS-200 hyper-fast MOSFET power switch and the CMD-100 galvanically isolated current measurement device, alongside the A1110 Plus Edition adding Ethernet, sensing, and adjustable output resistance as standard.
Its underlying technology rests on linear precision amplification capable of both sourcing and sinking current into reactive loads such as inductors and electric motors, complemented by sub-100 ns MOSFET-based power switching and galvanic isolation architecture (A1340-C1) for safe series/parallel stacking. All products are manufactured in-house at the Bochum facility (expanded to 2,000 m² in 2024) under an ISO 9001 quality management system maintained since 2008. An in-house apprenticeship program for electronics technicians, running since 2005, supplies most of the production workforce.
The business model is build-to-order direct hardware sales with unit pricing typically between €2,000 and €14,000 (and quote-based for A1500 systems and custom OEM versions), supplemented by paid application consulting for complex integrations. Go-to-market is sales-led via a website inquiry helpdesk with same-day response, supported by a technical content library of whitepapers and application notes; the company does not sell through distributors or online marketplaces. Customers are enterprise R&D laboratories, automotive manufacturers and Tier-1 suppliers requiring LV124/VW80000-compliant test systems, EMC testing facilities, and battery and fuel cell research labs. Leadership transitioned in 2022 with Jan Hubert joining founder Dr.-Ing. Manfred Hubert as Managing Director, completing a family-business handover with no external institutional ownership.
