Microwave Absorbers

Product highlights

- Can be used at higher frequencies than traditional shielding

- Can be used with other shielding to extend frequency range

- Variety of types for custom solutions

- Easy installation with pressure sensitive adhesive into noisy cavities

- Can be used for reducing both EMI and radar cross section

- Internal EMI reduction, cavity resonance reduction, used in conjunction with board level shielding
