Profile: MAST Technologies designs, develops and manufactures RF, microwave and EMI absorbing materials for integration into military & electronics solutions. We are equipped with a spacious elastomer processing suite for batch mixing, calendaring, compression molding flat sheets and complex parts, precision sanding, and custom die-cutting. Tuned frequency absorbers, or resonant frequency absorbers, provide reflection loss at a discrete frequency, typically offering 20dB of attenuation. Tuned frequency absorbers offer narrow band absorption from 1 to 40 GHz. Cavity Resonance Absorbers are designed to exhibit high loss within a microwave cavity. The absorber will in effect lower the Q factor of the cavity by attenuating cavity oscillations, resonant frequencies, or harmonics. Cavity resonant absorbers attenuate energy at normal and high angles of incidence at frequencies from 1 to 20 GHz.
