Transmission Attenuation of HIREC® Coating The transmission attenuation of HIREC® was measured for high frequency radio signals. If you need help selecting the correct material, one of our epoxy resin and polyurethane technical sales staff will help you select the best material for your manufacturing project. As a rule, most manufacturers require that the magnet room to have at least 100dB of RF attenuation at the Larmor frequency. They have many benefits, including protecting a circuit stage from receiving a current that's too high. Tooling costs are high because only very precise masks and fixtures will ensure that the metal is applied to only the inner surfaces of the enclosure. RF attenuators can also improve impedance match, ensuring power transfer from source to load is optimised. RF Paint provides an electroconductive coating for the protection against high-frequency (HF) radiation and low-frequency (LF) electric fields. 005 0,13 10MHz - 6. putnam@navy.
