HEMP (high-altitude electromagnetic pulse) tested RF surge protector (also known as radio frequency surge suppressor or arrestor) series from PolyPhaser is in-stock and will ship the same day as purchased. Our HEMP tested RF surge protector series guards against electromagnetic pulse (EMP) at high-altitude typically caused by nuclear explosion. These coaxial radio frequency surge protector products are commonly used for radio and antenna installations to protect equipment at risk. High-altitude EMP protection devices are specially designed to pass the desired frequency while suppressing surge.

PolyPhaser high altitude electromagnetic pulse protection series for RF incorporates various technologies. Surge protector technologies used for these high-altitude EMP protection devices include: blocking cap and gas tube, hybrid, surge filter or surge filter and gas tube. This HEMP tested surge arrestor / suppressor series for RF / microwave operate within a range of frequencies from 10MHz to 2.7GHz with the power handling maximum of 1kW (model dependent).

Our coaxial HEMP surge protection device series for RF from PolyPhaser is available with 7/16 DIN and N Type connections and most are designed as a bulkhead configuration. These coaxial components are available in F/F and F/M genders depending on the model. The combinations of high-altitude electro-magnetic pulse coax connections are: 7/16 DIN F/F, 7/16 DIN F/M, N Type F/F and N Type F/M.

Low passive intermodulation (low PIM) HEMP protection devices are part of this expanding product line. In addition to surge protectors with low PIM, IP67 rated high altitude EMP suppression components are available in this category. Many of these PolyPhaser HEMP tested surge devices are compliant with REACH and/or RoHS.

As experts in highly specialized EMP / high altitude electromagnetic pulse protection filter technology for RF, we have become a valuable source for defense contractors to meet the requirements set by military standards. Our proven electro-magnetic pulse surge protector technologies have become the solutions for these demanding military specifications. With this accomplishment, PolyPhaser is also expanding our HEMP protection components to support commercial / industrial requirements as they decide their high-altitude EMP needs.

PolyPhaser supplies one of the best varieties of high-altitude electromagnetic pulse protection devices available for shipping the same day. We ship our HEMP protection product line from stock the same day you order them. PolyPhaser supports our customers with a sense of urgency while providing innovative lightning and surge protection solutions that ensure reliable operation of critical systems for a connected world.
