Why our HF absorbers make your system EMC-safe
High-frequency interference can significantly impair the functioning of electronics. Our RF absorbers offer an effective way to avoid reflections in the high-frequency range and thus reliably meet EMC requirements. This is particularly important in safety-critical areas such as sensors for autonomous driving, radar and lidar systems or in industrial control systems.
Through targeted material selection and customer-specific adaptations, our microwave absorbers offer high efficiency in the desired frequency band. They improve the signal-to-noise ratio, prevent incorrect measurements and ensure system reliability.
Protect your electronics against high-frequency interference – with our expert advice.
Product portfolio – The right absorber solution for every frequency
Narrow-band flat absorber – precise attenuation in the target band
Our narrowband absorbers are ideal for suppressing defined interference frequencies in narrow bands. They are ideal for applications in sensor technology and in the field of “Radio Detection and Ranging” (radar), e.g. for reducing internal resonances or for targeted attenuation of interference points.
For broadband applications in the entire high-frequency range, we offer high-performance broadband absorbers that absorb constantly over a wide frequency range. They are particularly in demand in antenna environments, test chambers or in automotive sensor technology.
Our cavity absorbers are designed to minimize reflections in enclosed spaces such as device housings or RF test environments. They are also indispensable in the field of “Light Detection and Ranging” (Lidar) to reduce intrinsic interference.
Fields of application: From radar to space travel – this is where our absorbers prove their worth
Our HF absorbers are designed for extreme requirements in a wide range of industries:
- Automotive industry: Optimized for applications in the field of “autonomous driving” – sensors in the car such as radar or ultrasonic sensors benefit from clear signal separation.
- Aerospace: Materials with low outgassing and high temperature resistance, ideal for applications at high altitudes or in a vacuum.
- Military technology: Highest requirements for corrosion resistance, vibration tolerance and thermal shock – testable quality for critical systems.
- Industry & research: Application in EMC laboratories, HF test chambers, control and regulation technology.
