Description
SMA Plug (Male) to SMA Jack (Female) | 2-Hole Flange Panel Mount | Screw-Lock | Brass Body
The ROSNOL AD-A1A25A-PT/911-91 is a precision-engineered SMA adapter designed for high-frequency applications from DC to 18 GHz with a 50 Ω impedance. It delivers exceptional electrical performance with VSWR ≤ 1.15, insertion loss ≤ 0.05√F (GHz) dB, and insulation resistance up to 3 mΩ. Rated for 480 V RMS test voltage and power handling up to 200 W at 2 GHz, this adapter ensures reliable signal integrity. The screw-lock coupling mechanism provides secure connectivity with coupling nut retention ≥ 270 N and durability of ≥ 500 mating cycles. Recommended torque ranges from 0.8 to 1.1 Nm, making it ideal for robust RF systems.Constructed with premium materials, the center contact is beryllium copper with gold plating over a nickel-phosphorus underlayer for superior conductivity and corrosion resistance. The body and coupling nut are brass with the same gold-over-nickel finish, while the insulator is PTFE for excellent dielectric properties. Silicone rubber gaskets enhance environmental sealing, and the assembly withstands temperatures from -65°C to +155°C.
ROSNOL’s precision-engineered RF connectors offer a competitive alternative to leading global brands. Manufactured in ISO 9001-certified facilities and fully compliant with RoHS and REACH standards, these products combine high quality with cost efficiency. Customization services for plating, materials, and mechanical design are available to meet specialized requirements.
