Microwave absorber sheet for high frequency (millimeter wave)

Nitto's microwave absorber sheet is thin and high absorbance at millimeter wave (mmWave, high frequency)

Absorbs up to 99% (-20dB) of the selected wave frequency. Superior durability to survive harshest of environments. Has an ultra-thin design. Utilized the reduce radar malfunctions. Easy place and stick instillation, effective on most surfaces. Ability to customize to target customer specific requirements.

Features

Performance

  • Frequencies Supported: 20~300 GHz (Includes 60GHz, 77GHz, 79GHz )

  • Absorption Characteristics: < -20dB (Reflection attenuation, Return loss(RL), S11)

  • Shielding Performance:< -20dB (Transmission atteunuation, Transmitting loss(TL), S21))

  • Total Thickness:   0.7mm ~

• Thin and highly absorbent: Ideal for reducing noise (ghosting) caused by multipath (multiple reflections) and electromagnetic interference.
 
• Film thinness: Contributes to maximize the measurement area.     
             
• Transparent Options: Product can be made transparent using our material technology, allowing it to be used on clear surfaces, such as glass or plastic.
 
• Clean: Product does not generate dust and is effective for maintaining microwave anechoic chambers and microwave boxes.
 
• Easy to apply: The product is flexible and stretchable, allowing it to be installed without additional adhesive. This makes easy to take quick countermeasures against reflections (noise sources), on the spot.
 
• Adhesive Option: If different type of adhesive is needed for better adhesion, Nitto has a wide variety of adhesive types to choose from.

Total thickness is as thin as 0.7mm.
Thin profile for effective space usage.
Adhesive coating is not required.   
Sheet can be applied immediate by peeling off the
release liner  on the back to reveal the adhesive side.
