Applications: HF technology

Data and signals are transmitted quickly using high-frequency technology – be it in mobile communication, data centres, building utility systems, medical technology or in the aerospace industry, And this is right where we come in: with our wires and strands, and our expertise in the field of HF technology. We offer a broad product portfolio tailored to your specifications – for successful use in any frequency range.

The right wire for efficient data transfer

Trouble-free signal transmission starts with the correct selection of wires and strands. We offer you comprehensive service and the best quality for your requirements. Using a high-frequency measurement method based on the diameter, we can detect faults ahead of time – before the product is sent to you for further processing. This allows us to guarantee that our wires and strands will function for the desired application and provide you with a measurement report for each coil.

wires for high frequency technology

Our product portfolio for the field of HF technology

Classic high-frequency strands made of lacquer-coated single wires

The individual wires are insulated from each other with lacquer coating and enable better transmission properties in the HF range thanks to their larger surface area (skin effect).

High-precision single wires as inner conductors for coaxial cables

These wires are produced on a specially developed system. The surface is cleaned during the production process. Depending on customer requirements, it is possible to carry out an FFT analysis during ongoing production to check for periodic flaws and/or measure the diameter over the entire running length. Both methods make it possible to predict the suitability of the HF wire for the planned application or frequency range.

Stranded wires made of single wires/multiple wires with highly conductive coating

The single/multiple wires are coated with highly conductive precious metals such as silver, optimising the transfer properties. Here too, it is possible to carry out an FFT analysis during ongoing production to check for periodic flaws and/or measure the diameter over the entire running length depending on customer requirements. Both methods make it possible to predict the suitability of the HF strands for the planned application or frequency range.

Stranded wires with exceptionally smooth (compacted) surfaces

The exceptionally smooth and clean surface of the strands optimises their wave impedance. We offer the following procedures for predicting the suitability of the RF strands for the planned application or frequency range: Depending on customer requirements, an FFT analysis can be carried out during ongoing production to check for periodic flaws and/or measure the diameter over the entire running length.

Strands with varying lay length

Strands with varying lay lengths are used to prevent periodic faults in the form of lay length influences. These can also be manufactured in combination with surface coatings made of highly conductive precious metals. In this case, it is possible to measure and document the diameter over the entire running length during ongoing production.

Our service in the field of HF technology

In-line diameter measurement with logging

The in-line diameter is measured during production using a single or dual-axis laser. The measurement frequency here is up to 5000Hz. This very high-frequency measurement ensures that the results will be exceptionally informative.

The diameter is measured and recorded over the entire production length. This makes it much easier to assign wires and strands for combination or further processing in the subsequent process.

FFT analysis with logging

Wires and strands suitable for high frequencies require a very homogeneous structure. In particular, periodic interference has a negative effect on signal transmission.

Analysis using Fast Fourier Transformation (FFT) is a mathematical method for evaluating measured values. Periodic deviations can be detected in production and subsequently optimised based on the parameter being monitored (such as diameter or vibration).
