Pyramidal Absorbers:-
- Tapered to point along with square base of uniform thickness.
- Height of these Absorbers type varies from 4” to 36” and has standard base size of 60 cm x 60 cm.
- Excellent Absorption under entire frequency range of 80 MHz to 40 GHz.
- Used to direct energy in given path.
- Polarization Sensitive & Maximum performance at grazing incidence angles.
- Height of these Absorbers type varies from 4” to 28” and has standard base size of 60 cm x 60 cm.
- Desirable for applications requiring high reflectivity performance with low forward scattering characteristics.
- Attenuation is high -25 dB to -45 dB from frequency band 2 GHz to 18 GHz as compared to rest type of absorbers.
- It is manufactured only in standard height of 4” with base size of 60 cm x 60 cm.
- High Attenuation from frequency range of 100 MHz to 18 GHz.
- Front surface of these Multilayer Absorbers reduces coupling effect and found application in interference suppression applications.
- Thickness of these Absorbers type varies from 2cm to 10 cm and has standard base size of 60 cm x 60 cm.
- Customized availability as per client’s requirement.
- High Attenuation from frequency range of 100 MHz to 18 GHz.
- Thickness of these Absorbers type varies from 1cm to 5 cm and has standard base size of 60 cm x 60 cm.
- Customized availability as per client’s requirement.
- Flat Coir sheet absorbers are light weight used in open environment interference suppression applications.
- Thickness of these Absorbers type varies from 1cm to 10 cm and has standard base size of 60 cm x 60 cm.
- Customized availability as per client’s requirement.
- Rigid block comprising of pyramidal Absorber covered all over with Low density Polystyrene Foam.
- Utilized to have walking provision inside chamber & each walk-on Absorber bear weight of single person.
- Customized availability as per client’s requirement.
- These are thin ceramic ferrite tiles with exceptional RF absorbing characteristics in the frequency range of 30 MHz to 1 GHz.
- Ferrites used to line anechoic chambers for radiated emissions (ANSI C63.4) and immunity (IEC 1000-4-3) testing. Used when high Absorption & Compact Size are required.
- Ferrites are inherently immune to fire, humidity & Chemicals providing reliable & compact solution for attenuating the plane wave reflections.
- These tiles can be combined with specially designed urethane foam pyramidal absorbers to extend chamber operation to above 20 GHz.
- Hybrid RF absorber designed for low-frequency EMI test rooms and anechoic chambers.
- The “hybrid” construction consists of specially-formulated urethane foam pyramidal or wedge absorber panels mounted on top of ferrite tiles.
- Resulting in almost all the performance normally seen with ferrite tiles alone in the 30 – 1000 MHz range, plus up to -30dB reflectivity from 1 – 20GHz.
- Thin broadband absorber with a dielectric material.
- Accepted in microwave and antenna fields.
- Fabricated using layers of carbon impregnated natural rubber.
- Will withstand temperatures from -40 to 120 degree C.
- Impervious to moisture and can be subjected to outdoor environments.
- Can be easily cut with a knife or die.
- Effective at high power levels.
- Frequency Range: - 100 MHz to 18 GHz
- Average reflectivity: -20 dB
- Withstand temperatures: -40 to 120 degree C.
- Power Handling: - 0.15 W/cm
- Base Dimensions: - 12” x 18”
- Weight: - 2.145 Kg (approx.)
- Density: - 80-85 g/cm
- Color: - Black
- Applied to surfaces to improve radar performance, reduce backscattering.
- Effective in reducing specular reflections as well as surface currents due to high magnetic loss properties.
- Used to modify antenna patterns, cover antenna feed supports, line antenna caps to reduce reflections.
