RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while typing up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...

NexTek Press Release 6-25-2007

NexTek's Breakthrough performance: The ultra-compact E-Class Series of SurgeGuard™ lightning arrestors for applications up to 6GHz.NexTek Announces a Major Breakthrough in Surge Capability @ 6 GHz

Pass DC at no sacrifice to 6 GHz RF Performance Miniature, ruggedized, dustproof and waterproof

Westford, MA, June 25, 2007 - - NexTek, Inc., the leading designer of best-in-class lightning protection and EMC / power conditioning products and services, announces the expansion of the E-Class Series designed for optimizing RF performance at frequencies up to 6 GHz. The E-Class Series sets new, breakthrough surge performance standards to 6 GHz, provides bi-directional protection and is also characterized by passing DC without any performance degradation. This ground-breaking family of ultra-compact SurgeGuard™ lightning arrestors is specifically developed to meet the stringent demands of emerging RF applications including Ultra Wideband, Wi-Fi, WiMAX ground penetrating radar, surveillance, high speed communications systems, 5.0 - 6.0 GHz UNII, MMDS, WLL, IMS bands, public safety 4.9 GHz and HiperLAN.

The ultra-compact SurgeGuard E-Class Series is based on a gas discharge tube design packaged in two small geometry form factors designated PTCONFSAF09E and PTCONxONF09E. The miniature PTCONFSAF09E arrestors measure only 42 mm x 24 mm, have N-type to SMA-type connectors and can deliver a maximum of 30 W (48 dBm) of RF power at a maximum through-current of 5 A. The PTCONxONF09E arrestors measure only 50 mm x 24 mm, have N-type connectors and can deliver a maximum of 30 W (48 dBm) of RF power at a maximum through-current of 10 A.

All E-Class Series products include a 90V gas discharge tube and exhibit a nominal impedance of 50 Ω. Additional specifications include excellent lightning transient protection performance, low return loss (VSWR), top-rated materials, superb construction and are designed to be both waterproof and dustproof (IP68 Standard). The robust SurgeGuard E-Class Series provides a 10x multiple strike capability @ 5 kA and a 20 kA (8 x 20 μs) surge capability.

The E-Class Series is available with a variety of connectors including N(Female)-N(Female); N(f)-N(m); N(f)-SMA(f). The E-Class series of lightning arrestors is currently available and is value-priced in OEM quantities starting at $33 each.
