New development
We develop geometry, circuitry and integration based on your frequency bands, installation conditions and measurable target values.
CONTRACT DEVELOPMENT
Targeted optimization of the RF path on your circuit board.
We check and optimize circuit boards from the antenna connection to the RF chip. This includes component placement, line geometry, reference planes, ground and return current routing as well as all transitions between components, layers, cables and connectors. We provide support before the first prototype, in case of inadequate wireless performance and when redesigning an existing product.
01 / TECHNOLOGY & DEVELOPMENT
Check stack-up, impedance and return current paths
A nominal 50 Ω trace is not sufficient if reference planes are interrupted or connections and layer changes create strong discontinuities. We check the real circuit board structure including material, copper geometry, ground distances and manufacturing constraints.
- Microstrip and coplanar RF transmission lines, trace width, gap dimensions and distance to the reference plane.
- Continuous return current paths, ground connection, via fencing and transitions between layers.
- Insertion and return loss, coupling, resonances and parasitic effects of critical structures.
02 / TECHNOLOGY & DEVELOPMENT
Optimize transitions and component placement
We trace the complete signal path through antenna, matching, filter, LNA and radio chip. Pads, component terminals, connector launches, and coax connectors are considered electrical structures. Sensitive reception stages, clock sources, switching regulators and digital lines are arranged in context.
- RF chip/module output, matching network, filter and amplifier connections.
- Coax to PCB transitions, SMA launches, Micro-coaxial connectors and test adapters.
- Placement of matching, protection and decoupling components with short effective ground paths.
- Shielding, distances and decoupling between simultaneously operated radio paths.
03 / TECHNOLOGY & DEVELOPMENT
Combine simulation and measurement to clarify causes
We examine selected critical transitions using electromagnetic simulation and, if a prototype is available, compare them with measurements. This makes it possible to distinguish whether the cause lies in the antenna, a mismatch, line losses, coupling or the supply. Not every layout point requires the same model: the testing effort depends on the risk and target value.
- Structured visual inspection and commented layout review.
- 3D field simulation of critical structures with HFSS or CST and circuit analysis according to the task.
- S-parameters, isolation, decoupling and comparison of assembly/matching variants.
- Examination in the actual device housing and with the intended cable routing.
04 / TECHNOLOGY & DEVELOPMENT
Document changes in an actionable manner
You receive specific locations for changes, prioritized by technical effect. We can coordinate the proposals with your layout team or undertake an agreed redesign. After building the modified prototypes, we check whether the measures improve the intended properties.
- Commented layout views and justified recommendations for changes.
- Specifications for stack-up, placement, routing, ground, transitions and matching.
- Coordinated layout data, simulation results and measurement report in the agreed scope.
- Consideration of component assembly, test points and production documents.
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 receive an RF layout review with prioritized findings or a revised layout with documented boundary conditions and agreed comparison with measurement results. New development, optimization of existing PCBs and integration or customization of existing RF components are possible.
FREQUENTLY ASKED QUESTIONS
Technical questions about collaboration.
When is an RF layout review worthwhile?
Before the release of the first prototype and in the event of insufficient range, weak GNSS reception, unexpected attenuation, harmonics or mutual interference between several radio services. An early review can reveal critical areas before PCB production.
Does the entire circuit board have to be redeveloped for this?
No. We narrow down the affected signal path and check whether targeted changes to placement, matching, reference planes or transitions are sufficient. A complete redesign is only agreed as a separate scope.
What documents do you need?
Circuit diagram, PCB layout, layer stack and material data, parts list and, if possible, mechanical drawings, samples and existing measurement results. We coordinate the exchange of confidential data directly.
