Description
SMA Termination Load Plug (Male) with Heatsink | DC to 18 GHz | 50 Ω | 20 W
The ROSNOL T-A15-18G20WA/9XX is a high-power 50 Ω RF termination rated for 20 W average power at 25 °C, operating from DC to 18 GHz with VSWR ≤ 1.25 (≥ 19.1 dB return loss). Mechanical integrity includes screw-lock coupling, ≥ 500 mating cycles, center-contact captivation ≥ 20 N, coupling test torque 1.70 Nm max, and recommended torque 0.9 Nm. A black anodized aluminum heatsink ensures efficient thermal dissipation for extended high-power operation.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, telecom infrastructure, and instrumentation requiring robust power handling and broadband impedance stability.
ROSNOL RF components are manufactured under ISO 9001-certified processes and fully comply with RoHS and REACH regulations. Combining high build quality with competitive pricing, ROSNOL products provide a reliable alternative to leading European and American brands, with full customization services for materials, plating, and mechanical design.
