RAT type wave-absorbing material is the thin and flexible, operating wavelength ratio d/λ is about 0.05. The frequency band is quite narrow and good performance to absorbing at the resonant frequency, relative bandwidth of 15%, 25%, 35% to -15dB, -13dB And -10dB.The oblique incidence angle of incidence in 30°, the Rw is change small and performance declined slightly to 45° incidence angle, when 60°angle of incidence, the vertical polarization is about -7dB, horizontal polarization is about -13dB.
RL type wave-absorbing material is rubber raw material made for waveguide terminal load. good performance to absorbing, anti-aging, flexibility and easy to installation, suitable for low power. Standard waveguide BJ-320, 220, 180, 140, 120, 100, 84, 70, 58, 48, 40, 32, 22 is varying of the length of the load. Can can also be customized to the non-standard waveguide load according to customer requirements.The load test can be used to measure of lines to measuring and sweep test method. when installed, pls use the XY-401 glue to stick the surface of load and waveguide, and pressure the load after dry.

SAM type wave-absorbing material is component of pyramidal and transition layers with the ferrite materials, have the better absorption performance in 30MHz~18GHz. SAM pyramidal be equal to SA type of the flame retardancy, physical properties and environmental performance. Available adhesives affixed to the ferrite surface, for small EMC darkroom. The SAM-400, 500 use for 3m darkroom, the SAM-600, 700 use for 5m darkroom, the SAM-1000 use for 10m darkroom. SAM-type pyramidal tip also can be truncated height of about 20%, to save space. The SMT type is constant performance in low-frequency, but can dropped of about 10dB in high-frequency performance.
RAT type Broadband rubber plate absorbing materials use in a wide frequency band by 2GHz~18GHz, the main properties as follows:It's generally must be affixed to the metal substrate, the use of temperature -50~100. if the thickness increases, the electrical properties also can be improved. can custom-mode in 1~18GHz frequency. RAT-2~18G-2.5mm composite to 3mm with foam, thickness is 5.5mm, weight 8.5kg/m2, have the better performance in 1~18GHz.
