Unique Technology in Perfection
Frankosorb® technologies has been convincing with excellent and consistent performance for over 30 years.
Frankonia’s absorber technology uses the unique nano-thin film technology, which was developed in the early 90’s by Professor Günter Nimtz and Achim Enders at the University of Cologne. The research is based on the absorption properties of thin two-dimensional layers on polyethylene films.
Together with Frankonia, these fundamental research results were further developed in order to generate and manufacture a new type of absorber material.
The Frankosorb® absorber technology combines a variety of high-performance standards in a single solution. Due to the consistent performance and the unique property of non-combustibility, a safe environment for people and test objects can be guaranteed.
The unique method of Frankosorb® technology and its specific manufacturing process is available either as a hybrid solution in combination with Ferrite absorbers, or as a stand-alone pyramid solution with a length up to 2,4 m. Based on our R&D focus dedicated to the automotive industry, the Frankosorb® unique A2 non-combustible characteristics are also available for antenna chambers.
Frankosorb® – At a Glance
Today, Frankonia’s Frankosorb® unique absorber technology is the only solution existing on the world market, that is…
Aligned with the individual customer requirements, Frankonia anechoic chambers are lined with high-performance Frankosorb® hybrid absorber or short-/ long-pyramid configurations.
In accordance with Frankonia’s modular and prefabricated standards, the Frankosorb® Hybrid Absorbers are fixed to the shielding using screwing or clamp methods. The complete structure can therefore be adapted to future requirements at any time and is also reversible.
Together with the unique Frankosorb® absorber technology, Frankonia anechoic chambers are the best choice for long-term investments.
Frankosorb® – Unique Features
Frankosorb® – People safety and laboratory protection
Frankosorb® – Eco and user-friendliness
Due to the stable performance characteristics and its unique non-combustible attribute, a safe environment for people and EUT can been assured, which also leads to a constant, reproducible, and long-lasting testing quality.
Frankosorb® – Absorber Types
Frankosorb® Pyramid Series
The Frankosorb® pyramid absorbers are Frankonia’s unique an all-in-one solution typically from 30 MHz to 18/40 GHz. They are available either as short-pyramids P600 and P900 or as long-pyramids P2000, P2200, or P2400.
The most important advantage of the Frankosorb® long pyramid absorbers is the coverage of the whole frequency range starting from 26 MHz up to 40 GHz, so that additional Ferrite absorbers are unnecessary.
In order to enable a modular and modern installation of the pyramid absorbers, a clip-in substructure is installed on the inside of the shielding, into which the short or long pyramids with their specific size are securely hung. This means that the overall construction remains adaptable, and absorber can be removed one absorber at a time; nothing is glued or welded.
Frankosorb® Hybrid Series
The Frankosorb® Hybrid Absorber Series are a combination of ferrite tiles with its typical frequency range of 30MHz- 1GHz, and in addition, short hybrid-pyramid absorbers, which are extending the typical frequency range up to 40 GHz.
The Ferrite tiles are prefabricated in factory on support plates with a size of 600 x 600 mm to provide a modular and modern installation screwing method. Thus, the gap between the ferrites is almost eliminated, and which helps to improve the performance in the low frequency range.
The prefabricated ferrites modules are screwed onto an internal substructure in a horizontal grip of 600 mm. The additional Frankosorb® Hybrid Absorber lining with improved impedance matching is also made with screwing installation method using a special fixation kit.
The overall construction remains adaptable and removable piece-by-piece; nothing is glued or welded.
Next Generation Hybrid Turbine Absorbers
The Frankosorb® Turbine next generation hybrid absorbers are classic hybrid setups in combination with Ferrite, but due to their modified size and shape, they significantly boost the low performance requirements. Depending on the performance characteristics and customer preferences, our hybrid chambers will be equipped with the next-generation turbine absorbers.
The performance is program and part of the name: H1300 Turbine or H1600 Turbine
Frankosorb® HF Series
Frankonia’s brand new Frankosorb® absorber generation is the unique HF-Absorber series, which is dedicated for the automotive industry with focus to full vehicle antenna chambers as well as OTA, near field (NF) and far field (FF).
The latest absorber development is based on the existing Frankosorb® technology out of the EMC range and is classified as A2 non-combustible. Due to different measurement aspects, several versions have been considered to cover essential frequencies and their specific performance levels.
