Description
FME Plug (Male) to N Jack (Female) | Straight Design | Screw-Lock | Brass Body
The ROSNOL AD-E1N25A/14-H4 is a precision RF adapter designed for DC to 2 GHz applications, ensuring stable signal transmission with 50 Ω impedance and VSWR ≤1.43 (≥15 dB return loss). Insertion loss remains minimal at ≤0.1 × √F (GHz) dB, while insulation resistance reaches ≥5 GΩ for superior reliability. The adapter supports a test voltage of 1000 V rms and a working voltage of 500 V rms. Coupling is achieved through a secure screw-lock mechanism, with mechanical endurance of ≥500 mating cycles on the N side and ≥300 on the FME side.Constructed with premium materials, the N side center contact is phosphor bronze with gold plating over a nickel-phosphorus underlayer, while the FME side uses brass with identical plating structure. Both bodies are brass with copper-tin-zinc alloy finish, and PTFE insulators provide excellent dielectric stability. The adapter withstands temperatures from -65°C to +165°C and offers strong corrosion resistance.
ROSNOL combines exceptional quality with competitive pricing, making these RF components an ideal alternative to leading European and American brands. All products are manufactured under ISO 9001-certified processes and fully comply with RoHS and REACH standards. Customization services for plating, materials, and mechanical design are available to meet specialized interconnect requirements.
