Description
SMA Termination Load Plug (Male) with Heatsink | DC to 12 GHz | 50 Ω | 20 W
The ROSNOL T-A15-18G20WA/133 is a 50 Ω RF termination designed for DC to 12 GHz operation, supporting 20 W average power at 25 °C with VSWR ≤ 1.25 (≥ 19.1 dB return loss). Mechanical features include screw-lock coupling, ≥ 500 mating cycles, center-contact captivation ≥ 20 N, coupling test torque 1.70 Nm max, and recommended torque 0.9 Nm. The integrated black anodized aluminum heatsink enhances thermal management for sustained high-power performance.Materials and Plating: centre contact—beryllium copper with gold plating (non-magnetic nickel–phosphorus underplating); body—stainless steel, passivated; insulator—PTFE; gasket—silicone rubber; coupling nut—stainless steel, passivated; heatsink—black anodized aluminum. Suitable for RF/microwave test benches, telecom systems, and instrumentation requiring reliable broadband matching under elevated power conditions.
ROSNOL RF components are precision-manufactured in ISO 9001-certified facilities and comply with RoHS and REACH. Delivering dependable performance and cost-effective pricing, ROSNOL products offer a strong alternative to major global brands, with customization available for materials, plating, and mechanical configuration.
