Description
SMA Plug (Male) to SMA Jack (Female) | L-Adapter | Brass Body
The ROSNOL ASL-A1A25C/944-94 is a compact SMA L-adapter engineered for RF applications up to 18 GHz. It features a screw-lock coupling mechanism, ≥500 mating cycles, coupling nut retention ≥270 N, axial captivation ≥17 Ncm, and radial ≥3 Nm. Electrical performance includes 50 Ω impedance, VSWR ≤1.15 (≥23.13 dB), insertion loss ≤0.04×√F(GHz) dB, and RF leakage ≥100 dB up to 1 GHz. It supports power handling up to 200 W @ 2 GHz, with insulation resistance ≥5 GΩ and test voltage of 1000 V rms.The adapter is constructed with a brass body and coupling nut made of copper-tin-zinc alloy, a beryllium copper center contact with 3 µinch gold plating over 80 µinch non-magnetic nickel-phosphorus underplating, PTFE insulator, and silicone rubber gasket. It performs reliably across a temperature range of -65°C to +165°C.
ROSNOL’s precision-engineered solutions offer a competitive alternative to products from leading manufacturers in Europe, the USA, and other global markets. All ROSNOL components are manufactured in ISO 9001-certified facilities and fully comply with RoHS and REACH regulations, ensuring environmental safety and global regulatory alignment. Customization services for materials, plating, and mechanical design are available to support specialized requirements across a wide range of RF and microwave applications.
