Coaxial Surge Protector SMA Female to SMA Female, DC to 3 GHz

The 106-PCM-SP-DC3.SA2SA1 is a coaxial surge protector designed to sit inline between two SMA-female connectors, offering over-voltage protection for RF systems from DC through 3 GHz. It diverts lightning-induced spikes safely to ground while preserving the 50 Ω impedance match, keeping insertion loss below 0.2 dB and VSWR under 1.2:1. Constructed from nickel-plated brass with gold-plated contacts, this free-hanging unit meets IP67 sealing and operates between –40 °C and +85 °C, making it suitable for both indoor comms cabinets and exposed tower installations.

Its compact 47 × 25 × 25 mm form factor and support for more than 500 mate-demate cycles ensure it fits neatly into telecom backbones, satellite ground stations and wireless infrastructure. Installers and network operators benefit from straightforward integration and ongoing protection against transient surges, reducing equipment damage and downtime in critical RF links.
