SMA Male to SMA Female Lightning Arrester - DC - 6 GHz

Product Overview

This inline SMA Male to SMA Female protection unit is intended for 50 ohm coaxial paths from DC to 6 GHz. A replaceable 90 V gas discharge tube, rated at 10 kA for the 8/20 us waveform, guides transient energy toward the ground lug. During normal RF service, the element remains high impedance and the listed insertion loss is 0.3 dB.

Core Trade-off: This gas-discharge layout offers a replaceable protector with a low-capacitance transmission route. Its triggering behavior differs from diode approaches, while the listed form serves compatible antenna-line installations.

Protection Mechanism and Construction

• Protection Component: The central enclosure contains a replaceable 90 V gas discharge tube with a 10 kA reference rating on the 8/20 us waveform. The element can be reached for service without disconnecting the cable.
• Earth Bond Route: A side ring terminal connects the product to the earth bar. Ground-lead length and routing influence the energy that can continue toward downstream hardware.
• Housing Form: The inline brass body uses corrosion-resistant plating and can be placed within a compatible cable path.

Connector Interface: SMA male and female interfaces connect to compatible cable assemblies; use the relevant connector torque guidance.

Reference Technical Specifications

The following figures are reference information for this SMA Male to SMA Female lightning arrester. Confirm them against the selected manufacturing setup before deployment.

These figures apply to this protection family and require confirmation against the selected manufacturing setup.

Engineering Comparison

• vs. Quarter-Wave Stub: A quarter-wave stub is tied to its chosen frequency and a narrow DC-grounded band. This SMA configuration is specified from DC to 6 GHz for suitable multiband coaxial links.
• vs. Diode-Based Protector: Diode limiters can add capacitance that affects frequency and power capability. This GDT unit lists 0.3 dB insertion loss and 100 W reference CW handling for applicable RF lines.
• vs. DC Block Surge Protector: A DC block does not create the same high-energy earth path. This product directs a transient toward its grounding connection in applicable outdoor antenna installations.

Applications

• Module and Instrument Connections: For RF modules, instrumentation, small-cell, and CPE connections, this SMA unit can be placed in an antenna path to route induced surge energy toward earth before it reaches downstream hardware.
• Tower and Rooftop Installations: At a cabinet or shelter cable entry, the unit can form the grounded protection point for the transmission line.
• Multi-Band Radio Sites: The stated DC to 6 GHz range supports suitable earlier and current RF bands without changing the device configuration.
• Equipment Racks and Test Systems: Placed near a compatible equipment input, the product helps direct cable-coupled transients away from RF modules or instrumentation.

Installation and Grounding Notes

• Grounding First: For RF module and instrumentation installations, connect the ground lug to the earth bar with a short practical lead. Avoid long or thin connections because earth-path routing affects the installed result.
• Placement: Install the inline body at the relevant cable-entry protection point, keeping the ground terminal accessible within the site protection arrangement.
• Torque and Sealing: Tighten connectors according to manufacturer guidance. At outdoor interfaces, use appropriate weatherproofing tape or a weather boot.

OEM and B2B Support

• Configuration Requests: For volume requirements, connector combinations, alternative discharge options, and special plating can be considered.
• Assembly Availability: Factory-terminated jumper assemblies with a pre-installed protection unit may be supplied for compatible installation requirements.
• Packaging Options: Protective packaging, custom labels, and batch test reports may be requested.

FAQ

Q: How often does the gas discharge tube need replacement?

A: The 90 V element has a 10 kA rating on the 8/20 us waveform. After a major event, test the element and replace it if leakage is present or the hold-off test is unsuccessful.

Q: Will this SMA Male to SMA Female lightning arrester affect my DC - 6 GHz signal?

A: The listed values are 0.3 dB insertion loss and VSWR up to 1.35, supporting a low-impact RF path for applicable antenna-line use.

Q: Can I use this arrester indoors?

A: Yes. It may be installed at an equipment-side cable position or an entry location where another grounded protection stage is required. A SMA Male to SMA Female lightning arrester should match the selected cable interfaces and grounding route. This RF surge protector is intended for the listed 50 ohm coaxial arrangement. Verify that the 6 GHz coaxial lightning protection range matches the planned RF system. For RF modules and instrumentation surge protection, place the unit at a suitable equipment-side or cable-entry location. A second SMA Male to SMA Female lightning arrester reference can be used when documenting the selected assembly. Review cable support, connector access, weather sealing, and the earth-bar connection before commissioning. Confirm final configuration and site grounding before commissioning. During review. Before installation, identify the cable entry, available equipment clearance, mounting position, and path to the site earth bar. Check that the SMA interfaces remain accessible for inspection and that the cable is supported on both sides of the inline body. At exposed locations, inspect weather sealing, cable support, and the condition of the enclosure entry. Record the selected installation point and grounding connection with the system documentation. During maintenance, review the ring terminal, connector engagement, cable jacket, and physical access around the device. If the cabinet layout, RF module location, or coaxial route changes, recheck the mounting arrangement and ground connection before returning the line to operation. These site checks support the listed product configuration and do not replace final production information or applicable installation procedures.
