Description
SMA Jack (Female) to SMA Jack (Female) | 4-Hole Flange Panel Mount | Screw-Lock | Brass Body
The ROSNOL AD-A1A25A-PF/911-91 is a high-performance SMA adapter designed for RF and microwave systems operating from DC to 18 GHz with a 50 Ω impedance. It delivers VSWR ≤ 1.15, insertion loss ≤ 0.05√F (GHz) dB, and insulation resistance ≥ 5 GΩ, ensuring superior signal integrity. Rated for 1000 V RMS test voltage and power handling up to 200 W at 2 GHz, this adapter guarantees reliable 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 excellent conductivity and corrosion resistance. The body and coupling nut are brass with gold-over-nickel finish, complemented by PTFE insulators for dielectric stability and silicone rubber gaskets for environmental sealing. This adapter withstands temperatures from -65°C to +155°C, ensuring durability in harsh conditions.
ROSNOL’s precision-engineered RF connectors offer a cost-effective alternative 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.
