Rosenberger Messtechnik Sachsen Gmbh: A Full-range Supplier of Measurement Technology

PublishTime： 2020-12-06 Article Source：Rosenberger

Since its foundation in 1991 ROSENBERGER Messtechnik Sachsen has been a valued partner for research and development in high-frequency measurement technology. As a full-range supplier of measurement technology, the company provides comprehensive value-added supply chains and supports its customers throughout the entire process from development and design, prototyping and first samples, through to small series production.

Customers can count on definite performance commitments that deliver real added value:
Development and construction, HF design
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 construc-tion techniques.

At all times, developers at Rosenberger Messtechnik Sachsen 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 Messtechnik Sachsen 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 Messtechnik Sachsen 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.
