Description
SMA Jack (Female) to SMA Jack (Female) | 4-Hole Flange Panel Mount | Screw-Lock | Brass Body
The ROSNOL AD-A1A25B-PF/911-91 is engineered for high-frequency applications from DC to 18 GHz with a 50 Ω impedance. It achieves VSWR ≤ 1.15 and insertion loss ≤ 0.05√F (GHz) dB, ensuring minimal signal degradation. Rated for 1000 V RMS test voltage and power handling up to 200 W at 2 GHz, this adapter provides robust electrical performance. The screw-lock coupling mechanism ensures secure connectivity with ≥ 500 mating cycles and recommended torque of 0.8 to 1.1 Nm.Material construction includes beryllium copper center contacts with gold plating over nickel-phosphorus underplating for superior conductivity. The body and coupling nut are brass with gold-over-nickel finish, complemented by PTFE insulators and silicone rubber gaskets for environmental sealing. Designed to withstand temperatures from -65°C to +155°C, this adapter offers durability and corrosion resistance.
ROSNOL’s RF solutions combine high quality with affordability, making them ideal replacements for major European and American brands. Produced under ISO 9001-certified processes and fully compliant with RoHS and REACH regulations, these connectors ensure global environmental standards. Customization options for plating, materials, and mechanical design are available to support unique application needs.
