SMA Jack (Female) to SMA Jack (Female) | 4-Hole Flange Panel Mount | Screw-Lock | Stainless Steel Body

The ROSNOL AD-A2A25A-PF/9X-9X is a high-performance SMA adapter designed for RF and microwave systems operating from DC to 18 GHz with a 50 Ω impedance. It offers VSWR ≤ 1.15, insertion loss ≤ 0.05√F (GHz) dB, and insulation resistance up to 3 mΩ, ensuring minimal signal degradation. Rated for 480 V RMS test voltage and power handling up to 200 W at 2 GHz, this adapter guarantees robust electrical performance. The screw-lock coupling mechanism provides secure engagement with ≥ 500 mating cycles and recommended torque between 0.8 and 1.1 Nm.

Constructed with premium materials, the center contact is beryllium copper with gold plating over nickel-phosphorus underplating for superior conductivity and corrosion resistance. The body and coupling nut are stainless steel with passivated finish, while PTFE insulators deliver excellent dielectric stability. Designed to withstand temperatures from -65°C to +155°C, this adapter ensures durability in demanding environments.

ROSNOL’s precision-engineered RF connectors deliver exceptional quality and cost efficiency, serving as reliable alternatives to leading global brands. Manufactured in ISO 9001-certified facilities and fully compliant with RoHS and REACH standards, these products guarantee quality and environmental safety. Customization services for plating, materials, and mechanical design are available to meet specialized requirements.
