Plant Radeberg

 

Since its foundation in 1991, Rosenberger Messtechnik Sachsen has developed into a valued partner for research and industry in the field of high-frequency measurement technology. 

As of July 2023, Rosenberger Messtechnik Sachsen GmbH and the parent company in Fridolfing will operate jointly under the name Rosenberger Hochfrequenztechnik GmbH & Co. KG. This decision represents a sustainable basis to secure the specific strengths of the Radeberg site as a plant and to continue to be successful together.

As a full-range supplier for measurement technology, Radeberg consistently maps comprehensive value chains and accompanies its customers throughout the entire process - from development and design to the production of prototypes and initial samples to series production.

For specific requirements, individual solutions can also be developed and built in a timely and cost-optimized manner. The Radeberg site has local know-how and competence and at the same time benefits from the global network of the Rosenberger Group.

 

We offer our customers concrete performance commitments that deliver real added value:

  • HF design, development and construction from a single source
  • Prototypes, sample production and series production
  • Complete service on-site
  • Reliability and long-term partnership
  • Technical sales consulting for measurement technology products

 

 

From Prototype to Series Production

New developments typically start with CAD construction for mechanics together with simulations of the resulting RF features. Alternatively, a simulated RF line can be used as the starting point for a CAD design. Prototype part production is then performed using CNC lathes as well as conventional sample construction techniques.

At all times, developers at the Rosenberger plant in Radeberg monitor the sample and part production process and take corrective action if necessary. The extensive vertical production capabilities enable the manufacturing of single parts on CNC automatic lathes through to the refinement of raw components and assembly with testing of finished parts. Small series are produced at the development site in Radeberg while larger series can be transferred to subsidiaries within the Rosenberger Group.

Rosenberger in Radeberg develops individual solutions for demanding projects with specific requirements. As a result, it is constantly establishing new fields of competence. If necessary, the development resources available at Rosenberger’s headquarters in Fridolfing, and elsewhere in the Group’s global network, can be called upon.

Certified Precision and Reliability

Passive RF components and measuring equipment from Rosenberger are manufactured from high-quality materials,  characterized by highest precision, quality and reliability:
coaxial precision components for calibration and verification as well as components with built-in resistors such as attenuators, mismatches and termination resistors.

 

Development, test and QA departments, measurement laboratories of well-known companies as well as universities and research institutes have been relying on products from Radeberg for many years. Metrological institutes such as the PTB in Braunschweig and METAS in Bern are also among its long-standing customers.

Product optimization for:

  • Stability and reproducibility
  • Precise VSWR and damping values
  • Bandwidths up to 110 GHz

Highest mechanical precision and extensive controls with the latest measuring technology are a matter of course for Rosenberger and reinforced by the Group’s ISO 9001 certification.  However, quality means much more than supplying faultless products day in day out. The continuous optimization of all processes in terms of time and costs is also crucial.

 

Extensive Portfolio

In addition to customized components manufactured in smaller batches in Radeberg, the Radeberg site offers an extensive range of products for Rosenberger's overall portfolio.

 

The range of calibration and verification components, attenuators, mismatches and terminating resistors includes:
Other HF components:
  • Precision connectors for coaxial cables and adapters within and between series
  • Customized assembled cables, especially semirigid, for highest demands up to an operating frequency range of 110 GHz
