LOPU’s LP-ET510 is an ultra broadband absorber which has been optimized for EMC applications. LOPU manufactures ET510 from high quality, low density polyurethane foam. A Trible immersion process evenly impregnates the foam with a proprietary conductive carbon formula. This process optimizes absorber performance greatly. Full individual quality assurance checks take place during production.

This absorber features truncated-tips, which allow for greater working space within the chamber, while reducing the chances of absorber tip damage

features truncated-tips, which allow for greater working space within the chamber, while reducing the chances of absorber tip damage

Features

New or Retrofit Chamber Installation

LP-ET510 Anechoic Absorber can easily be installed into either new construction, or as a retrofit to existing chambers.

Reduced Profile, Truncated-Tips

The LP-ET510 has a reduced profile, providing the user a greater working space within the chamber.

Truncated-tips on this absorber reduce the chance of absorber tip damage.

Non-Hygroscopic Substrate

The LP-ET510 absorber is produced from a fire- retardant chemical formula that is non-hygroscopic. As a result, the absorber is not affected by moisture and will maintain its mechanical and RF performance over the life of the product.

Assorted Colors

The LP-ET510 is now available in the dark blue, black, grey or other customized colors.

Performance Standards

LP-ET510 absorber meets or exceeds MIL-STD- 461D/E/F and RTCA-D0-160 performance requirements and is ideal for new installations or chamber retrofits. It provides an ultra broadband performance range of 80 MHz to 40 GHz without use of ferrite tiles.

Ultra-Broadband Performance

During the manufacturing process, our unique two- step impregnations are specially formulated to provide improved reflectivity performance below 200 MHz. This tuning is verified on each absorber piece in a large coaxial reflectometer which measures reflectivity vs. frequency from 80 MHz to 300 MHz to ensure consistency of performance.

Power Handling

LP-ET510 has excellent power handling capabilities. This absorber has been proven to safely withstand up to

1500 Watt/m2 CW power density in RF and microwave frequency ranges. Maximum service temperature is 90o C (190o F) continuous.

Standards

This absorber meets the fire retardant standards of NRL 8093 Tests 1, 2, 3, UL 94, and DIN 4102-B2:

Tests for Flammability. LP-ET510 has an GB/T2406-9384-84 oxygen index of 29 and belongs to flame retardant B2 level(GB8624-1997).
