Description
BMMA Plug (Male) to SMA Plug (Male) | Straight Design | Slide-Lock & Screw-Lock | Stainless Steel Body
The ROSNOL AD-BM1A15A/9X-9X is a precision RF adapter for 50 Ω systems, operating from DC to 18 GHz with VSWR ≤ 1.20 (≥21 dB return loss) and insertion loss ≤0.03 × √F (GHz) dB. Electrical ratings include operating voltage of 350 Vrms and dielectric withstanding voltage of 1000 Vrms. Coupling combines slide-lock for BMMA and screw-lock for SMA, ensuring secure engagement with ≥500 mating cycles per side. Recommended torque for SMA is 0.5 N·m.Materials and plating: center contacts are beryllium copper with 3 µin gold plating over 80 µin nickel-phosphorus underplating. Bodies are stainless steel with passivated finish; insulators are PTFE. Rated for −65 °C to +125 °C, this adapter offers excellent corrosion resistance and mechanical durability.
ROSNOL delivers precision-engineered RF adapters for uncompromising performance in high-frequency and microwave applications. Manufactured under ISO 9001-certified processes, fully RoHS and REACH compliant, and offering cost-effective alternatives to leading brands. Customization for materials, plating, and mechanical design is available to meet specialized interconnect requirements.
