TDK RF Solutions
TDK's baseline semi-anechoic 10-meter chambers are designed to provide an optimal environment for radiated emissions and radiated immunity measurements.
Our baseline semi-anechoic 10-meter chambers are designed to provide an optimal environment for radiated emissions and radiated immunity measurements in full compliance with many industry standards such as ANSI C63.4, EN 50147-2, CISPR 12, CISPR 16, CISPR 22, SAE, and many more.
With TDK’s history and experience as the original inventor of hybrid RF absorber technology (ferrite tile + foam RF absorber) and being the only test chamber company to manufacture both the ferrite tiles and the foam RF absorbers, we are in a unique position to warrantee the best possible anechoic validation performance values.
With our standard configuration, we target +/-3.5dB NSA and +5.5dB sVSWR performance. You can rest assured our NSA, sVSWR, and Field Uniformity measurement results will provide you with unmatched reliability, repeatability, and the highest performance environment possible that exceed industry compliance regulations.

Notes:
1)This design assumes up to a 45cm (18”) raised ground plane floor inside the chamber for ease of cable management and installation of a flush turntable.

TDK materials are lightweight, yet rigid and quite strong. TDK RF absorber material will not droop, crumble, breakdown, or change their physical or electrical characteristics even after 20+ years of use.
Our ISO-9001 and ISO-14001 facilities provide a tightly controlled manufacturing process assuring every part is consistent and avoids uneven resistive material distribution problems frequently observed in competitor materials.
TDK materials are also extremely safe and naturally very clean. You will not have to worry about potential fire hazards or toxicity issues with TDK materials.
A unique advantage TDK can offer you is the basis for our solutions stem from the fact TDK not only provides turnkey installations for our customers but TDK also owns and operates these same chambers to research, develop, test, and validate the many other products TDK manufactures.
As a firsthand user of test chambers for R&D and compliance testing of various products, we have a true understanding of the challenges you face. In addition to our simulation and modeling expertise to predict how a particular design will perform, we can share our experience with you to optimize the chamber design for the most practical, efficient, and real world use.
An example of actual 10m chamber measured NSA performance is shown in the graph (below). TDK can achieve very stable and consistent swept frequency values across the entire test volume area. An example of our commitment to performance and results, TDK owns and operates a 10m chamber in our internal R&D lab that achieves an NSA value of ±1.0 dB.
An example of potential sVSWR performance is shown in the graph (below). With minimal set-up time and an optimized quantity of floor absorber between the sVSWR measurement antennas, TDK can achieve very stable and highly consistent swept frequency values across the entire test volume (quiet zone) area. sVSWR performance is accredited from 1 GHz to 18 GHz and for reference information, testing can be extended to 40 GHz.
An example of potential Field Uniformity performance is shown in the graph (bottom). With minimal set-up time and an optimized quantity of floor absorber between the Field Uniformity measurement antennas, TDK can achieve very stable and highly consistent swept frequency values across the entire test plane surface (quiet zone) area. Field Uniformity performance and validation testing can be extended to 18 GHz.
