New development
We develop the geometry, circuit and integration around your frequency bands, installation conditions and measurable performance targets.
CUSTOM DEVELOPMENT
Active antennas: developing the radiator and receiver frontend together.
We combine antenna development with low-noise amplifiers, filters and power supply design. Especially with weak received signals, the entire chain determines the usable signal quality.
01 / TECHNOLOGY & DEVELOPMENT
Receiver performance starts before the LNA
Losses between the antenna and the first amplifier directly affect the system noise figure. We design the matching, filter placement and cable route together with the LNA.
- The passive antenna, input filter, LNA and subsequent RF stages as one receiver path.
- GNSS antennas and active receiver assemblies for a defined frequency plan.
- Combined assessment of gain, noise figure, selectivity and immunity to interference.
02 / TECHNOLOGY & DEVELOPMENT
Power supply, protection and connections
An active antenna requires controlled separation or combination of the power supply and RF signal. We account for power supplied through the coaxial cable or a separate connection, as well as the intended mechanical installation.
- Bias tee, decoupling and supply filtering.
- Protection circuits, shielding and unwanted feedback.
- RF connectors, coaxial interfaces and PCB transitions.
03 / TECHNOLOGY & DEVELOPMENT
Testing the active assembly
In addition to the antenna, we characterise the amplifier path. Measurements use the agreed supply and integration conditions; limits are defined for each project.
- Antenna matching, efficiency and radiation pattern.
- Gain, noise figure, linearity and intermodulation.
- Filter attenuation and the effects of the feed cable.
THREE ROUTES TO THE RIGHT SOLUTION
Develop a new design. Optimise an existing solution. Customise products.
Optimisation
We analyse existing samples and documentation, identify the causes of losses or insufficient performance, and implement targeted changes.
Product customisation
We assess an existing Sevskiy solution and adapt its frequency tuning, connectors or installation. We can undertake volume production on request.
OUR APPROACH
From requirements to a tested design.
- 01
Requirements and interfaces
We clarify the frequency plan, available space, mechanical environment, supply, connections and test criteria. Existing CAD data, schematics and measurements are included in the assessment.
- 02
Design and simulation
We compare suitable concepts, design the circuit or geometry, and simulate critical electromagnetic structures and transitions.
- 03
Prototypes and measurement-based refinement
We build prototypes, measure under defined conditions and refine the design by comparing the model with the actual assembly.
- 04
Design approval and volume production
We document the agreed configuration and test plan. Production support and volume manufacturing are agreed as required.
YOUR DELIVERABLES
Technically documented and ready for the next development step.
You receive an optimised active antenna solution with electrical and mechanical interfaces, a power-supply concept and agreed measurement data. Volume production can be included as a further scope of work.
FREQUENTLY ASKED QUESTIONS
Technical questions about working with us.
Does more gain always improve reception?
No. System noise figure, selectivity and dynamic range are decisive. Excessive gain can overload downstream stages; later amplification cannot undo losses before the first LNA.
Can an active production antenna be customised?
Yes. We assess frequency tuning, filtering, gain, power supply, cables, connectors and the required integration work.
