New development
We develop geometry, circuitry and integration based on your frequency bands, installation conditions and measurable target values.
CONTRACT DEVELOPMENT
Develop circuits for RF modules and networked devices.
We develop electronic assemblies from the circuit concept to the characterized prototype. The radio part, microcontroller, sensors, power supply and interfaces are coordinated with the antenna, filter, amplifier and circuit board layout. We take on a completely new development, optimize your existing circuit or adapt an existing Sevskiy assembly to your requirements.
01 / TECHNOLOGY & DEVELOPMENT
Translate system requirements into a schematic
We clarify function, radio standard, frequency bands, signal level, supply, power consumption and installation space. From this we derive the assembly architecture and the electrical interfaces. We select components based on the required function, their RF properties and the intended integration.
- Selection and wiring of radio SoCs, transceivers, microcontrollers, crystals and passive components.
- Supply concept, decoupling, protective circuitry, sensor connection and device interfaces.
- Circuit diagram, parts list and definition of the interfaces to antenna, mechanics and firmware.
02 / TECHNOLOGY & DEVELOPMENT
Design the complete RF signal path
We view the connection from the antenna via matching, filter, LNA and coax connection to the radio chip as one connected signal path. Insertion loss in front of the first amplifier, interference signals, feedback and parasitic effects of the real components influence the achievable system performance.
- Matching networks, filters, low-noise receive amplifiers and active antenna circuitry.
- Bias networks, signal distribution, power dividers, couplers and feed networks according to the task.
- Joint evaluation of gain, noise figure, linearity, selectivity and supply.
- Circuit analysis and electromagnetic examination of critical lines and junctions.
03 / TECHNOLOGY & DEVELOPMENT
Develop circuit and circuit board together
We convert the circuit into an RF-compliant PCB layout. We take stack-up, controlled impedance, short return current paths and the spatial separation of sensitive reception stages from digital interference sources into account. The antenna is matched with the circuit board, case and battery.
- Component placement, ground and decoupling concept, controlled RF lines and layer changes.
- Coax to PCB transitions, connector launches and appropriate measurement/test access.
- Antenna integration and coexistence of multiple radio services in the target device.
04 / TECHNOLOGY & DEVELOPMENT
Build, measure and specifically improve a prototype
We equip and put functional models into operation. The measurements depend on the module: for example S parameters, filter characteristic, gain, output power or reception behavior. Deviations between circuit concept, simulation and sample are systematically attributed to circuit, supply, layout and installation environment.
- Iterative optimization of component values, matching, ground routing and shielding.
- Documented measurement results and traceable changes to the circuit diagram and layout.
- Production documents, testing concept and, if requested, mass production of suitable assemblies.
THREE WAYS TO THE RIGHT SOLUTION
New development. Optimization of existing designs. Product customization.
Optimization
We analyze existing samples and documents, determine the cause of losses or inadequate performance and implement targeted changes.
Product customization
We check an existing Sevskiy solution and adjust frequency tuning, connections or installation. We can handle mass production upon request.
OUR APPROACH
From the requirement profile to the tested version.
- 01
Requirements and interfaces
We clarify the frequency plan, installation space, mechanical environment, supply, connections and test criteria. Existing CAD, circuit and measurement data are incorporated.
- 02
Design and simulation
We compare suitable concepts, design the circuit or geometry, and simulate critical electromagnetic structures and transitions.
- 03
Sample and metrological comparison
We build prototypes, measure under defined conditions and fine-tune the design based on the comparison between the model and the real structure.
- 04
Release and mass production
We document the agreed design and test plan. Production support and management of mass production are agreed as required.
YOUR RESULT
Technically documented and ready for the next step.
You will receive the agreed circuit and layout documents, parts lists, functional models and measurement data. The scope can include a complete radio assembly or the targeted processing of an individual receive, filter, amplifier or supply path.
FREQUENTLY ASKED QUESTIONS
Technical questions about collaboration.
Can you improve existing electronics instead of developing new ones?
Yes. We check the circuit diagram, layout and existing samples, narrow down the cause of the error and work out specific changes. If an existing Sevskiy assembly is suitable, adapting it may also be an appropriate starting point.
What do you need to start the project?
Functional description, wireless standards and frequency bands, target values, supply, installation space and interfaces. For an existing device, circuit diagrams, parts lists, layout data, housing drawings and previous measurements help.
Do you also develop circuit board and antenna?
Yes. We coordinate the circuit, RF layout and antenna together to the real installation environment and can take over prototypes, measurements and the agreed series implementation.
