DMC Broadband Ferrite absorbers
DMC Ferrite based electromagnetic wave absorber are used with combination of ferrite tiles. It has operating frequencies from 30 MHz to 40 GHz and thanks to its compact size, the Ferrite Series is suitable for maximizing chamber internal space.
DMC Ferrite tiles for EMC Chamber and Antenna Chamber
DMC Ferrite tiles are precision machined to have almost zero dimensional tolerance which helps in proper alignment of tiles, reduce gap between tiles resulting in better performance and Normalized site attenuation of EMC chambers per ANSI C63.4 and applications per CISPR 16-1-4 and IEC 61000-4-3
| Ferrite absorbers are used to absorb electromagnetic waves and reduce reflections inside EMC and antenna test chambers, ensuring accurate RF measurements. |
| Ferrite absorbers typically operate from 30 MHz to 40 GHz, providing broadband electromagnetic absorption. |
| High-quality ferrite absorbers can provide reflectivity levels up to about −50 dB, depending on frequency and absorber design. |
| Ferrite tiles are mainly effective in the 30 MHz to 1 GHz low-frequency range, where traditional foam absorbers are less effective. |
| Ferrite tiles absorb low frequencies while foam absorbers absorb higher frequencies. Together they create broadband absorption for EMC compliance testing. |
| They are commonly used in EMC chambers designed according to ANSI C63.4, CISPR 16-1-4, and IEC 61000-4-3 testing standards. |
| Typical ferrite absorbers can handle around 1.8 kW/m² RF power, making them suitable for high-power testing environments. |
| Yes. Many ferrite absorbers comply with NRL-8093, UL-94, and DIN fire-safety standards for safe operation in test facilities. |
| Precision machining ensures minimal gaps between tiles, which improves absorption performance and ensures accurate EMC measurements. |
| They reduce RF reflections, create a controlled electromagnetic environment, improve measurement accuracy, and support EMC compliance testing. |
