RF & Microwave Absorbing Materials

RF and microwave absorbing materials are used to absorb/attenuate high frequency signals. When an RF/Microwave signal passed though an absorbing material, the signal level gets attenuated. These materials are available in various formats - Sheets, Pyramids, Wedges etc. and are designed to absorb RF/Microwave signals up to a specific frequency. Different materials have different levels of attenuation. So when selecting the right materials for absorption the following parameters should be considered:

Configuration: This is the form factor of the absorbing materials. It can be in the form of a sheet, pyramid, wedge or something else.

Frequency: This is the frequency range up to which the material is required to absorb signals. Different materials are designed for different frequency ranges.

Attenuation: This is the level of absorption that the material provides. It is usually measured in dB. So if a sheet has absorption specified to be 30 dB, 10 dBm signal that is incident on it will become -20 dBm be the time it gets past the sheet.

everything RF has listed  RF/Microwave absorbing materials from the leading manufacturers. View product specifications, download datasheets or request a quote. A quote requested on everything RF will be routed to the company and their distributors and sales reps in your region. This way you do not need to go through the hassle of finding out who you need to contact.
