The SEA HYT from Siepel is an RF Absorber that operates from 30 MHz to 40 GHz. It is designed to optimize the usable space inside anechoic chambers while maintaining the performance required by industrial and defense EMC standards such as CISPR/EN 14-16 and MIL-STD-461. This absorber utilizes a hybrid truncated design and provides high reflectivity performance over a wide frequency range when glued to ferrite tiles. It can handle an input power of 2 kW/m2. 

The SEA HYT absorber measures 605 x 605 mm (base) and also supports customization of the design to suite different testing requirements. This RoHS-compliant hybrid absorber is ideal for EMC testing applications.
