Description

Vous cherchez un expert RF capable de sécuriser vos performances radio et d’accélérer vos phases d’intégration et de validation ? J’accompagne des projets 4G/5G, micro-ondes et RU/RRH sur l’architecture système RF, la linéarisation PA (DPD/CFR), la validation de performance (EVM, ACLR, BER, spectral masks), l’intégration CPRI/eCPRI et l’automatisation de bancs de mesure. J’interviens aussi bien en support R&D qu’en phase de debug, industrialisation et préparation au release, avec une forte culture du résultat, de la mesure et du root-cause analysis.

ABTICS
RF Systems Architect
avril 2025 - Aujourd'hui (1 an et 2 mois)
Villebon-sur-Yvette, France
Contributed to the national FlexSoGreenXG program, where ABTICS develops an indoor RU. Technical
focus on system integration and verification readiness:
• • Defined RU integration architecture and bring-up approach across RF, baseband and software layers,
focusing on stable interfaces and verification readiness.
• • Led fronthaul integration activities (CPRI/eCPRI) and ensured RU behavior is compatible with O-RAN /
Open Fronthaul interoperability expectations (integration checklists, debug hooks, repeatable procedures).
• • Specified key timing/clock-domain constraints and integration requirements to de-risk system closure and
support industrialization handover.
• • Translated standards/requirements into RU-level KPIs + acceptance criteria (EVM/ACLR/BER,
SEM/masks, power/sensitivity) and structured the verification plan with traceable evidence.
Spectronite
Senior RF Application Engineer
octobre 2022 - mars 2025 (2 ans et 5 mois)
Maisons-Laffitte, France
Developed point-to-point microwave links (up to 10 Gbps over 150 km) and drove system performance
closure from bench to release sign-off:
• • Owned end-to-end system performance closure from bench definition to release sign-off: EVM/ACLR/BER,
spectral emissions and masks, sensitivity/power trade-offs.
• • Delivered DFE/RF solutions for linearity and waveform readiness (CFR/DPD + impairment compensa
tion), improving spectral regrowth while maintaining high-order modulation performance (up to 1024-QAM
where applicable).
• • Built repeatable verification procedures and automated measurement campaigns (Python/SCPI +
MATLAB) to accelerate regression, reporting, and root-cause analysis.
• • Partnered with cross-functional teams (HW/FW/embedded/industrialization) to convert test evidence
into release decisions and manufacturing readiness.
NEXT TECHNOLOGIES' INNOVATIONS
RF Engineer
novembre 2020 - octobre 2022 (1 an et 11 mois)
77200 Torcy, France
Contributed to indoor Cloud-RAN RRH/RU (3GPP 4G/5G) R&D, from architecture to end-to-end
integration and performance closure:
• • Contributed to indoor RRH/RU system design and integration closure for 4G/5G contexts, linking RF chain constraints to measured KPIs.
• • Implemented and evaluated CFR/DPD behaviors and connected algorithm settings to system metrics
(EVM/ACLR/BER) and RF chain limitations.
• • Supported integration bring-up and RCA using RF impairment signatures (IQ/DC/CFO, constel lation/spectrum patterns) and created reproducible embedded environments (Embedded Linux/Yocto,
toolchains).
