For years many companies have relied on the department of high-frequency technology of Prof. Heuermann to develop and build demonstrators/ prototypes which offer professional answers to all kinds of specific problems. HHF build on a broad spectrum of experience and competence to deal with any future challenges and issues in an innovative and comprehensive manner.
Heuermann HF-Technik GmbH considers exchange of know-how and personal customer relations to be the very foundation for a holistic problem-solving competence.
The competence is also based of a lot of publications. The leading german RF-book for engineers includes the modern RF technology including basics, passive RF-components, transmission lines, mixed mode S-parameter, filters and resonators, switches, amplifiers, noise, measurement systems, fitting of components. The reference to this paper- or e-book for RF technology from Prof. H. Heuermann is:
