RF Services

Transform electromagnetic waves and their constraints into added value for our customers.


You must :

  • Develop or integrate products with a radio component
  • Optimize design, consumption, performance and costs
  • Make electronic products RADIO compliant
  • Carry out characterization, normative or investigative tests
  • Develop or integrate products with a radio component

NEXIO brings you expertise and support for technological choices, design assistance, investigation, numerical simulation, technical documentation, and qualification.

We intervene in your laboratory to carry out alone, in teams or on a platform, testing and laboratory management activities.

Our missions are customized from 1 day to several months.
