In front of deindustrialisation of the French electronic industry in the nineties, Gilles PICARD had the dream to set up his own firm, in disruption with the global strategic tendency of larger organisations to end with French manufacture.

With 25 years of experience in Thomson CSF as successively engineer, technical manager and then commercial manager, he decided to set-up DETI in 1995, in collaboration with his daughter, Aude PICARD, newly graduated in international business.

They together set up the firm and got in association with other engineers with many decades of hands-on experience in microwave design and industrial technologies.

DETI then began operation designing and manufacturing passive custom RF and microwave filters, duplexers and subassemblies for military and commercial markets.

The company, since then, developed a reputation for producing very reliable parts for the military industries: Very wide frequency bands, low loss and high power performance were what set DETI apart from its competitors.

In 2012, Gilles went to retiree and Aude PICARD became general manager, after 17 years as administrative and financial manager.

In 2019, she became major owner and Chairperson of the company. DETI can be considered as a Woman Owned Small Company, despite this certification doesn’t exist in France.

The managing pool is completed by Emmanuel Michaut, Deputy Director and Commercial Manager and Sylvain Mellaza as Technical Director.


Today, DETI has widened his range to the whole DC-50 GHz band and produces RF and microwave solutions serving niche segments such as ground satcom, radars, electronic warfare and EMC testing. DETI’s offer includes, among others, custom and standard filters, power dividers, directional couplers and high power combiners. Their design is based on the best combinations of technologies to meet the specifications: core technologies, microstrip, stripline, suspended substrate, coaxial or waveguide.
