Polypropylene (pp) based hybrid pyramid absorber

polypropylene pp based hybrid pyramid absorber icon 1

Series

Polypropylene (pp) based hybrid pyramid absorber is a product that is optimalized to be used in a EMC chamber and is available in a different range of sizes. When used with ferrite tile 3600, the 3700 series has a broadband operating frequency range starting from 30 MHz and up to 40 GHz.

Due to the carbon powder synthesis technique the pyramids are having a a high high uniformity of carbon powder density throughout the absorber. The product has almost no carbon dust, so applicable for clean test sites and it has low maintenance cost.
