Description
BMA Plug (Male) to SMA Jack (Female) | 2-Hole Flange Mount | Slide-On & Screw-Lock | Stainless Steel Body
The ROSNOL AD-BA1A25A-PT/9X-9X is a precision RF adapter for 50 Ω systems, operating from DC to 18 GHz with VSWR ≤ 1.25 (≥19.08 dB return loss) and insertion loss ≤0.05 × √F (GHz) dB. Coupling combines slide-on for BMA and screw-lock for SMA, ensuring secure engagement and long-term reliability. Rated for −65 °C to +165 °C, this adapter supports robust performance in demanding environments.Materials and plating: center contacts are beryllium copper with gold plating over nickel underplating. Bodies and outer contacts are stainless steel with passivated finish; insulators are PTFE. This construction provides 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.
