Radio frequency absorbers (RF absorbers) have many uses in the communications industry. From broadband to antennae and from high power to low, the RF absorber soaks up energy.

Commercial and military applications use RF microwave absorbers, RF absorbers and wireless RF absorbers in areas such as radar and other types of communication. RF absorbers are very thin and flexible. You can use them indoors or out. They come in various shapes including:

1. RF component absorbers such as the High Performance Broadband Pyramidal RF Absorber that often work in free-space chambers. Its shape produces an impedance gradient yielding high performance and reflectivity levels.

2. RF microwave absorbers such as the Truncated Pyramidal RF Absorber, which is similar to the High Performance Broadband, but fits in chambers with the top removed.

3. High Performance Wedge RF absorbers, which look like a wedge, that make products sensitive to polarization and also reduce backscatter in chambers.

Save money on RF absorbers equipment

When you buy used or refurbished equipment from a RF absorbers supplier, you save money and often get a chance to exchange the equipment, if it's not completely satisfactory in performance. Other ways to reduce cost include renting or leasing. Equipment availability varies with used and refurbished vendors, so if your product isn't available, try again at a later date.

I recommend: TESLA buys and sells equipment at reduced prices. They also offer customers the option of leasing equipment. Test Equipment Connection offers refurbished electronic equipment, including modulators. This company supplies products for customers around the world, carries thousands of products and also gives you the option of trading in or selling your used equipment.

Purchase from a manufacturer specializing in RF absorbers equipment

Find RF and microwave absorbers for your business from manufacturers with a history of product quality and innovation. Companies with ISO certifications must pass ISO requirements for standard and quality.

I recommend: Microsorb Technologies offers RF products for defense and commercial purposes. It commits to customer satisfaction and timely delivery of product. FerriShield, an ISO 9001:2000 certified manufacturer of RF absorber equipment, offers customers RF pads and other absorber products.

Expand your options by purchasing from a RF absorbers manufacturer with a large, varied inventory

Look for a manufacturer carrying numerous designs to find the RF absorbers material for sale that best suits your purposes. Specifically look for companies that constantly expand inventory and ask what new products are available in the near future.

I recommend: Cuming Microwave, formed to offer customers high-quality RF products, employees a dedicated staff. The manufacturing company, 3M, is a worldwide supplier of RF/microwave absorbers and other electronic components. It offers clients easy, online shopping and a large selection of product.
