RF Microwave Pyramidal Antenna test Absorber

Broadband Polypropylene RF Microwave Absorber

DMC-PP-MI series are high performance Polypropylene RF Microwave absorber covering wide band frequency range. The appearance and characteristics are similar to HY series, but PP-MI series has been specifically designed for best performance at Microwave frequency range. Therefore, this PP-MI series of absorbers are highly preferred for Antenna Pattern Measurement (APM), Compact Antenna Test Range (CATR), Radar Cross Section (RCS) and Electronic Warfare Test (EWT) application.

Broadband Polypropylene RF Microwave Absorber features:

Frequency range 80MHz to 100GHz
Typical reflectivity as high as -50dB
Plug and Pull install
Power handling capacity 4.8kW/m², 1353 V/m CW Radiated field strength
Fire Retardant per NRL-8093 1,2,3, UL 94:2013, HBF and DIN 4102 and Class B2
Continuous working temperature up-to 120°C
Clean Room suitable per ISO 14644 Class5
Water Resistant per GB/T 4208-2017
RoHS and REACH Compliant
Zero Carbon dust
