Description
2.92mm Jack (Female) to SMA Jack (Female) | Straight Design | Screw-Lock | Stainless Steel Body
The ROSNOL AD-K2A25A/9X-9X is a precision RF adapter designed for high-frequency applications up to 18 GHz. With a 50 Ω impedance, it achieves a VSWR of ≤1.15 and insertion loss of ≤0.05 × √F (GHz) dB, ensuring superior signal integrity. The screw-lock coupling mechanism provides secure engagement, while mechanical durability exceeds 500 mating cycles. Recommended torque ranges from 0.8 Nm to 1.1 Nm, and center contact captivation meets stringent axial force requirements for robust performance.Constructed from premium materials, the center contacts are beryllium copper with 3 µinch gold plating over an 80 µinch non-magnetic nickel-phosphorus underlayer for excellent conductivity and corrosion resistance. The body and coupling nut are stainless steel with passivated finish, and PTFE insulators ensure dielectric stability. A silicone rubber gasket enhances environmental sealing. The adapter operates reliably across a temperature range of -55°C to +125°C.
ROSNOL’s RF adapters deliver exceptional quality and cost efficiency, making them a reliable alternative to leading global brands. All products are manufactured in ISO 9001-certified facilities and fully comply with RoHS and REACH regulations. Customization services for plating, materials, and mechanical design are available upon request.
