Key Specifications
Description
BMA Bulkhead Plug (Male) to SMA Jack (Female) | Straight Design | Slide-On & Screw-Lock | Stainless Steel Body
The ROSNOL AD-BA1A25A-BH/9X-9X is engineered for 50 Ω systems, supporting DC to 18 GHz with VSWR ≤1.14 (≥23.69 dB return loss) and insertion loss ≤0.09 × √F (GHz) dB. Electrical specifications include withstanding voltage of 1000 Vrms and RF leakage of −60 dB at 2.3 GHz. Contact resistance is ≤4 mΩ for center contacts and ≤2 mΩ for outer contacts. Coupling uses slide-on for BMA and screw-lock for SMA, ensuring secure engagement with ≥500 mating cycles per side. Recommended torque for SMA is 0.9 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; gaskets are silicone rubber. Rated for −65 °C to +165 °C, providing excellent corrosion resistance and mechanical reliability.
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.
