Product Spotlight: Ultra-Wideband Coaxial Arrestor – 5.2-18.0 GHz


NexTek’s portfolio of available Coaxial Surge Arrestors covers a wide range of potential applications, ranging from DC (0 hz) to 18GHz at a wide level of RF Power levels.  However, there is one device that is uniquely suited and positioned to provide industry-leading protection for microwave, satellite, and other high frequency applications within the 5.2-18.0GHz range.  With an extremely wide operating band, robust always-on quarter wavelength stub protection technology, and high RF Power handling rating…The QWSNFNF0500 is a unique solution designed for the most demanding of applications.

It features best-in-class performance specifications including bi-directional protection, low VSWR, high RF power capability, and ultra-low let-through energy. The passive, always-on character of quarter wave stub lightning protectors means that the QWS 0500 will protect effectively against both lightning and high-speed (HEMP/NEMP) type surge pulses. By using robust materials and construction, the maintenance free QWS 0500 series is ruggedized, weatherproof to IP68 standards, and can withstand multiple strikes as well as very high transients up to 60kApk.
