Key Product Information


​Non-Hygroscopic Substrate

ETS-Lindgren absorbers use a new fire-retardant chemical formula that is non-hygroscopic. As a result, the absorber is not affected by moisture and will maintain its mechanical and RF performance over the life of the product. Broadband Performance CV Series absorber is designed to provide good RF attenuation of incident electro- magnetic wave from L-Band to W-Band frequency ranges. 

Power Handling Capability 

CV Series absorber can safely perform in environments that generate field strengths up to 200 V/m with operating temperatures up to 90° C (190° F). 

Tested Performance 

CV Series absorber is tested for reflectivity performance using the Naval Research Lab (NRL) broadband swept frequency arch method. 

Fire Retardancy 

CV Series absorber meets applicable US government and commercial flammability specifications as verified by an independent testing laboratory.

Wedge Absorber ​ETS-Lindgren's Wedge Absorber effectively reduces reflections between 30 MHz and 100 GHz and its RF reflectivity levels are the same as its equivalent sized pyramid absorber. Wedge absorbers are used in areas of chambers where pyramid absorbers would provide too much backscatter under specific configurations.<br>
CRV Curvilinear Microwave Absorber <p>​ETS-Lindgren Curvilinear Absorber is an advanced new RF absorber product that is optimized for broadband reflection suppression. </p>
EHP High Performance Microwave Pyramidal Absorber <p>​ETS-Lindgren's type EHP (Extra High Performance) microwave absorber is designed for use over a wide frequency spectrum and has been used as an effective tool for the reduction of reflections from 30 MHz through 100 GHz. </p>
FF Filter Foam Absorber <p>​ETS-Lindgren's Filter Foam/Vent Absorber series microwave absorber is similar in appearance and geometry to conventional ETS-Lindgren pyramidal and wedge type materials, and is tested to the same rigid specifications. </p>
Flat Laminate Absorber <p>​ETS-Lindgren's Flat Laminate Absorber, a moderate performance broadband microwave absorber is a graded dielectric material that has been widely accepted in the microwave and antenna fields. </p>
HP High Power Microwave Absorber <p>​ETS-Lindgren High Power Microwave Absorber is fabricated from high temperature materials. </p>
Microwave Convoluted Absorber <p>​ETS-Lindgren’s EHP Convoluted Absorber is designed to provide good refectivity performance with low forward scattering characteristics at incident angles up to 60° from normal incidence at microwave and millimeter-wave frequency ranges. </p>
Walkway Absorber <p>​ETS-Lindgren's Extra High Performance Walkway Absorber is a special absorbent material that is compatible with anechoic chamber reflection requirements, yet provides a walking surface for personnel. </p>
