The LS Series 0.070″ thick RF absorber material is an iron-loaded silicone elastomer optimized for the S and C bands (3.5 to 6.5 GHz). Designed for superior cavity resonance reduction, it covers the mid-range of the LS Series frequency spectrum, targeting Wi-Fi, LTE, CBRS, and sub-6 GHz 5G applications.

At 0.070″ thick, this option bridges the gap between the 0.060″ and 0.080″ thicknesses. Thinner options at 0.050″ and 0.040″ shift performance higher. Thicker options at 0.100″ and 0.125″ extend coverage into L and S bands. For applications requiring a non-silicone alternative, consider the US Series acrylic elastomer.
