2.92mm Plug (Male) to SMA Jack (Female) Adapter, DC-18GHz VSWR1.15

2.92mm Plug (Male) to SMA Jack (Female) | Straight Design | Screw-Lock | Stainless Steel Body

The ROSNOL AD-K1A25B/9XX-9X is designed for high-frequency interconnects from DC to 18 GHz with 50 ohm impedance. It achieves a VSWR of ≤1.15 and insertion loss of ≤0.05 × √F GHz, ensuring minimal signal degradation. The screw-lock coupling mechanism provides secure connections with recommended torque of 0.8 to 1.1 Nm, center contact captivation of ≥20 N, and mechanical durability of ≥500 mating cycles for robust field reliability.

Engineered materials and plating deliver excellent conductivity and environmental resistance. SMA side: beryllium copper center contact with 3 microinch gold plating over 80 microinch non-magnetic nickel-phosphorus underplating, stainless steel body and coupling nut with passivated finish, PTFE insulator. 2.92mm side: beryllium copper center contact with the same gold over nickel-phosphorus plating stack, stainless steel body and coupling nut passivated, PS insulator, silicone rubber gasket. The adapter operates reliably from −55°C to +125°C, maintaining stable dielectric and mechanical performance.

ROSNOL’s RF adapters deliver precision, consistency, and value, making them a competitive alternative to major European and American brands. All products are manufactured under ISO 9001 certified processes and comply fully with RoHS and REACH. Customization for materials, plating, and mechanical design is available to support specialized interconnect needs.
