What Altum RF does
Altum RF is a fabless semiconductor company founded in 2019 in Eindhoven, the Netherlands, that designs and supplies high-performance RF to millimeter-wave monolithic microwave integrated circuits (MMICs) for advanced electronics systems. Its product portfolio spans GaAs and GaN-based power amplifiers, low-noise/driver amplifiers, distributed amplifiers, switches, and phase shifters covering DC to 150 GHz, with a catalog of 40+ parts from X-band to beyond 100 GHz. The company pioneered plastic over-mold lead-frame packaging at frequencies up to 44 GHz, enabling cost-efficient packaging at bands where it is not standard practice, and emphasizes a design-for-manufacture approach with full production test capabilities, JEDEC-qualified reliability testing, and ISO 9001:2015 certification across both its Eindhoven headquarters and Sydney Design Center.
The company operates a dual revenue model: catalog MMIC sales (bare die and packaged parts in QFN and laminate formats) through a global distribution network anchored by Richardson Electronics and 15+ regional sales representatives across EMEA, US, and Asia, plus custom and semi-custom MMIC development under NRE arrangements. Key end markets are SatCom (VSAT, LEO/MEO/GEO, NTN), telecom and 5G/6G infrastructure (up to E-band), test and measurement, aerospace and defense (AESA and phased-array radar, EW, missile guidance), and industrial/scientific/medical applications. Strategic differentiation rests on a leadership team drawn from MACOM, NXP, Philips, Nitronex, and Mimix Broadband, deep ties to the European space and defense ecosystem (two ESA contracts under ARTES, TNO co-development, POLARIS-NGF participation, SpaceNed membership), and foundry partnership with WIN Semiconductors for GaAs pHEMT and GaN-on-SiC HEMT processes.

Revenue model
- Catalog MMIC Product Sales: Altum RF generates revenue from a broad catalog of standard RF to millimeter-wave semiconductor products including power amplifiers, low-noise amplifiers, distributed amplifiers, and switches. Products are sold as bare die or in various package formats (QFN, laminate). Revenue is one-time per unit, with repeat orders as customers move from prototype to production.
- Custom/Semi-Custom MMIC Development: Altum RF develops custom or semi-custom MMIC products tailored to unique customer requirements. The preferred business model includes up-front NRE (non-recurring engineering) payment to cover development and fabrication costs, followed by delivery of initial prototype and early production quantities. Revenue is split between NRE fees and subsequent product deliveries.
