To meet the growing demand for RF lightning and surge protection for global 4G LTE and 5G network applications, PolyPhaser’s new SX™ series surge arrestors have an optimized design to meet the rigorous requirements of these high-end wireless networks. This new product line—four models with 4.3-10 connectors—covers a broad frequency range from 698 MHz to 2.7 GHz and provides market-leading, low PIM performance. The SX series has a typical PIM rating of −130 dBm (−173 dBc, 2 x 20 W), with 0.1 dB insertion loss and 28 dB return loss. Two of the models allow the pass-through of AISG signals.
The SX series uses PolyPhaser’s patented spiral inductor surge protection technology, a unique spiral inductor that responds almost instantaneously to a lightning surge while maintaining optimal RF performance. PolyPhaser’s technology enables these RF lightning and surge arrestors to outperform quarter-wave stub and gas tube technologies. These surge arrestors are compact; compared to bulky, quarter-wave stub RF arrestors, they occupy approximately 40 percent less space than traditional arrestors, making them well-suited for small cell networks and distributed antenna systems (DAS), as well as macro sites.
The 4.3-10 SX surge arrestors are bi-directional for ease of use and ship with a hardware kit that allows them to be bulkhead mounted. Weatherproof when installed, they are CE and RoHS compliant and meet IP67, Bellcore TA-NWT-000487 and Procedure 4.11, Wind Driven (120 MPH) standards.
PolyPhaser’s surge arrestors have been field tested and are deployed by major, global cellular carriers and in critical wireless communication systems used by police, fire and emergency responders.
