Nextek Launches Coaxial Wide Band 5.2 GHz to 18.0 GHz Lightning Protector for Microwave Applications

Optimized for C, X, and Ku Band Use Ultra Compact with minimal VSWR and insertion loss Ruggedized, weatherproof 60kA bi-directional transient surge protection

Westford, MA, October 14, 2011 – – NexTek, LLC., a leading designer of best-in-class lightning protection and EMC / power conditioning products and services, announces the development of a new line of SurgeGuard™ quarter wave stub lightning protectors. Designed specifically for Microwave frequency applications, the QWS 0500 sets a new standard of protection for coaxial applications in these bands. OEMs have begun installing the QWS 0500 series in wireless and satellite applications operating in frequencies ranging from 5.2 GHz to 18.0 GHz

NexTek’s SurgeGuard™ QWS 0500 lightning protector for microwave applications between 5.2 and 18.0GHz.

The QWS 0500 series is extremely compact, measuring only 67 mm (2.62”) in length X 23 mm (0.90”) in diameter N-type connectors and bulkhead mounting. 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.

The QWS 0500 SurgeGuard™ series of lightning arrestors is available now from NexTek, in N-type female bulkhead to N-type female connector configuration as P/N QWSNFNF0500. For more information or a datasheet with complete product specifications for this ground-breaking design, please visit
