About

Founded in 2019, Altum RF is a defense component supplier based in Eindhoven, Netherlands working in radar & sensors, electronic warfare, communications & satcom +1 more.

Altum RF is a semiconductor company that designs, models, packages and supplies RF to millimetre-wave monolithic microwave integrated circuits (MMICs) using GaAs and GaN technologies, from DC to about 150 GHz. Its portfolio includes low noise amplifiers, power amplifiers, driver amplifiers, distributed amplifiers, switches and phase shifters, offered as catalogue and custom or semi-custom products. Target markets include telecom and 5G/6G, satellite communications, radar, test and measurement, industrial, scientific and medical, and aerospace and defense. For aerospace and defense, the company supplies front-end ICs for AESA radar systems and amplifiers for electronic warfare, with a focus on SWaP-C and harsh-environment ruggedness. Altum RF manages the full supply chain from design through fabrication, packaging, test and qualification, and offers NRE-based development for custom products. The company is headquartered in Eindhoven, Netherlands, with sales and application support in EMEA, the United States and Asia.
