RADIO INTERFERENCE GUARD (RIG) LOW PASS RADIO FREQUENCY ATTENUATOR.

Abstract

The Radio Interference Guard (RIG) is a low pass filter which provides effective RF protection for electroexplosive devices. RF attenuation is obtained by propagation of electromagnetic radiation through a metallic barrier. The initial concept of the RIG was analyzed and DC and RF design parameters were established. Methods for complete electrical and environmental testing were devivised. After successful qualification to NWL specifications, 100 units were made in production with production tooling. All units surpassed the specification of a maximum attenuation of 9 db at DC and a minimum attenuation of 35 db at 100 KC. Average values obtained were 8.1 db attenuation at DC and 39.2 db at 100 KC. As a result of this study, a RIG device that provides effective RF protection for electroexplosive devices was successfully designed, tested, qualified, and manufactured. (Author)
