Artificial Intelligence
Artificial Intelligence is a strategic sector for the company. Today, SERMA Ingénierie works with latest-generation FPGAs to embed AI in image processing.
Embedded software
SERMA supports you right from the analysis of the specification.
Proactive and perfectly positioned to advise you about architecture, choice of OS, real-time kernels and communication protocols, our SERMA engineers are very familiar with development techniques such as DO178. They develop, document and qualify an extremely wide variety of software programmes and cover the following areas:
- Compliance with DO178
- Drivers, Firmwave
- Application software (algorithms, control laws)
- Boot loader
- HMI, Labview
- Board Support Package
- C, C++, ADA
- Certification
RF Technology
SERMA Ingénierie is responsible for the development and manufacturing of high-performance, complete systems and sub-systems for wireless telecommunication infrastructures.
Full Transmitter/Receiver chains
SERMA develops full transmission and reception chains ranging from 100MHz to 6GHz.
Based on platforms that combine both digital and analogue devices (FPGA, DAC, ADC, Transceiver/Receiver), these chains are able to:
- Generate and receive signals
- Convert up and down frequencies (mixers, LO, etc.).
- Perform modulation and demodulation of signals
- Highly sensitive, thanks to LNAs with a low noise factor
These chains are also agile in terms of frequency: SDR (Software Defined Radio).
RF power amplifiers
SERMA develops RF power amplifiers ranging from several milliwatts to several hundred Watts.
They enable us to achieve extremely accurate results, via skilled handling of:
- The various types of transistor technologies: LDMOS, GaN, etc.
- Advanced amplifier architecture techniques: Class AB, Doherty Amplifier, Asymmetric Doherty Amplifier, etc.
These amplifiers also enable us to achieve high levels of linearity thanks to the use of error correction technologies:
- Analogue-corrected amplifiers (Feedforward, Cartesian Feedback)
- Digitally-corrected amplifiers (Digital Pre-Distortion, CFR)
CAD
SERMA Ingénierie has an electronics CAD department that masters the 4 key stages of modelling of components, schematic design, placement and routing and file generation.
Our CAD process for electronics offers:
- Expertise in printed circuit board technologies: Flex, multilayer, heat sink, SMI.
- Mastery of methodologies and compliance with standards: IPC 2221, IPC 2223, IPC 7351, NF 93713.
- Integration of “signal integrity” aspects: analysis during routing, post-routing analysis.
- Incorporation of industrialization constraints: Sectors (health care, automotive, aeronautics, rail, defense), EMS (reproduction of PCBs, assembly technologies, in-situ testing), EMC, manufacturability, in-house(capitalization and feedback).
- Taking charge of prototype production
Tools used
Our expert knowledge of CAD using tools such as Cadence (ORCAD ®, Allegro® PCB Design HDL, Allegro® PCB Performance, Allegro® PCB Routing), Mentor PADS®, Mentor Board Station ® (Design Architect), Mentor Expedition® (DxDesigner ExpPCB, Expedition Pinnacle, Library Manager, Fablink XE Pro) and ALTIUM® means we are able to produce complex circuits based primarily on:
- Stack-up: High-density multi-layers with μBGA on both sides
- Pitch: Fine-pitch BGAs of 0.8mm, 0.5mm, 0.4mm (HDI)
- Mixed-component assemblies and CMS (PTH/SMD)
- Holder: Epoxy, Kapton, Rogers, Flex, etc.
- Via: buried vias, laser vias, short-diameter through-holes
Signal processing
SERMA Ingénierie provides hardware and software development services for digital signal processing platforms.
Based on components such as FPGA, DSP, DAC, ADC, we provide you with assistance for these platforms focused on the development and implementation of:
High-speed protocols: CPRI, JESD, GbE/10GbE, PCIe
Real-time OSs: open-source or licensed
We are also fully skilled in the development of real-time signal processing algorithms, enabling for example:
