Description
SMA Termination Load Plug (Male) with Chain | DC to 18 GHz | 50 Ω | 2 W
The ROSNOL T-A15-18G2WB-88.9/H11 is a 50 Ω SMA termination with integrated safety chain for DC to 18 GHz operation, specified at VSWR ≤ 1.2 (≥ 20.83 dB return loss) and 2 W average power at 25 °C. Mechanical features include screw-lock coupling, ≥ 500 mating cycles, axial center-contact captivation ≥ 20 N, 1.70 Nm maximum coupling test torque, and recommended torque 0.8–1.1 Nm to ensure durable and repeatable connections.Materials and Plating: centre contact—phosphor bronze with gold plating (non-magnetic nickel–phosphorus underplating); body—brass with gold plating (non-magnetic nickel–phosphorus underplating); insulator—PTFE; gasket—silicone rubber; coupling nut—brass with gold plating (non-magnetic nickel–phosphorus underplating); safety chain—stainless steel, passivated. The safety chain is engineered to prevent accidental loss during installation or maintenance, keeping the termination tethered to panels or ports and helping mitigate foreign object damage risk. Ideal for RF test systems, network analyzers, and communication equipment that require secure attachment and broadband matching.
ROSNOL’s precision-engineered RF terminations are produced in ISO 9001-certified facilities and fully comply with RoHS and REACH. Offering high build quality and competitive pricing, ROSNOL products are an effective alternative to major global brands, with full customization support for materials, plating, and mechanical configuration.
