ABOUT E-REON
E-REON designs and builds custom, application-specific equipment in which RF performance, embedded control and physical integration are engineered together.
Founder-led and technically active, E-REON maintains senior engineering involvement from system architecture and mechanical design through integration, measurement and final delivery.
TECHNICAL LEADERSHIP
E-REON was co-founded in 2015 by Andreas and Vassilis Koroulis. Their complementary experience brings together RF and microwave system architecture with the multidisciplinary engineering required to realise complete hardware.
CO-FOUNDER
RF & Microwave System Architecture
An electronics engineer and RF and microwave system architect with more than 25 years of experience covering RF power amplifiers, RF front ends, radar and defence electronics, RF energy applications and system-level development.
CO-FOUNDER
Multidisciplinary Hardware Systems
A mechanical engineer and hands-on multidisciplinary R&D engineer with more than 20 years of experience developing RF, electronic and electromechanical hardware—from feasibility and system definition through physical design, prototype integration, verification and technical handover.
IN-HOUSE ENGINEERING
E-REON brings RF and microwave design, specialist assembly, system integration and measurement together within its own engineering environments. The same technical team can carry the requirements into the physical hardware and verify the completed result.
RF architectures, amplifiers, front ends, frequency conversion, passive structures and supporting electronics developed using circuit, electromagnetic, thermal and mechanical analysis as required.
RF boards and control electronics assembled using component-placement, vapour-phase soldering, inspection and rework capability for prototypes and repeatable low-volume builds.
RF modules, power distribution, bias, protection, embedded control, cabling, cooling and mechanical structures brought together as complete equipment.
RF performance, operating behaviour and thermal response measured during bring-up and verification, with the results used to refine the hardware before delivery.
COMPANY DEVELOPMENT
E-REON was established in 2015 from a shared commitment to turn advanced RF and microwave engineering into practical hardware.
Successive programmes extended that responsibility—from specialist RF design and prototype development to multichannel equipment, industrial RF systems and performance-critical defence applications.
Andreas and Vassilis Koroulis established E-REON, combining RF and microwave system architecture with multidisciplinary hardware engineering.
E-REON delivered its first multichannel RF-energy system, integrating multiple RF paths, control and physical hardware as one operating system.
The company expanded into industrial RF equipment developed for demanding operating environments and application-specific integration requirements.
A defence programme in drone communications extended E-REON’s work into secure, performance-critical RF links.
Current development includes RF hardware for radar and electronic-warfare systems, supported by expanded in-house assembly, integration and measurement capability.
E-REON TODAY
This progression has established E‑REON as a trusted engineering partner for organisations requiring application-specific RF and microwave hardware.
