Description
SMA Termination Load Plug (Male) with Heatsink | DC to 18 GHz | 50 Ω | 5 W
The ROSNOL T-A15-18G5WA/9XX is a high-power 50 Ω RF termination covering DC to 18 GHz with VSWR ≤ 1.25 (≥ 19.1 dB return loss), rated for 5 W average power at 25 °C. Mechanical characteristics include screw-lock coupling, ≥ 500 mating cycles, centre-contact captivation ≥ 20 N, 1.70 Nm maximum coupling test torque, and 0.9 Nm recommended torque. A black anodized aluminum heatsink enhances thermal dissipation for sustained power handling.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. Ideal for RF/microwave test systems, network analyzers, and communication equipment requiring stable impedance at elevated power levels.
ROSNOL’s precision-engineered RF terminations are produced under ISO 9001-certified quality systems and fully comply with RoHS and REACH. Combining high build quality with competitive pricing, ROSNOL products serve as an effective alternative to premium European and American brands, with full customization options for materials, plating, and mechanical design.
