product description
Hybrid Quarter Wave Surge Arrestor 698 to 2700 MHz 7-16 DIN female - female bulkhead
RFS Item Number: 7F7FB-HYB90-02
This 7-16 DIN style hybrid quarter wave surge arrestor with gas capsule for high-power and low IM application is foreseen for bulkhead mounting or in-line arragement with grounding wire connection (not included) via M8 thread. Surge arrestors are designed to protect wireless base stations, switching centers and transmission line from the damaging effects of extreme high voltage surges caused by lightning strikes. Lightning strikes, even on grounded systems, can implant crushing voltages on RF transmission lines, creating voltage spikes on the center conductor of coaxial cable and putting the network out of commission. These RFS lightning protection devices are designed and tested to the most demanding specifications. They are rated to protect against both direct and indirect multiple strikes in the harshest environments imaginable. Their rugged construction utilizes solid metal housings, spring bronze contacts and superior plating, which results in outstanding system protection and operating continuity.
FEATURES & BENEFITS
- Allows 2.176 MHz signal to pass for AISG systems
- Broadband operation - DC and RF (698-2700 MHz)
- DC continuity on center conductor for reliable operation (DC pass)
- Multiple strike protection provides current handling capability of 20 kA
- Replaceable gas capsules for easy maintenance
- Outstanding VSWR and IM performance
- Water resistant to IP67 standards (mated)
- Reverse installation possible without performance impact
