Description
BMA Plug (Male) to SMA Jack (Female) | Panel 4-Hole Flange Mount | Slide-On & Screw-Lock | Brass Body
The ROSNOL AD-BA1A25B-PF/91-91 is designed for 50 Ω systems, supporting DC to 22 GHz with VSWR ≤1.3 (≥17.69 dB return loss) and insertion loss ≤0.05 × √F (GHz) dB. Electrical ratings include working voltage of 335 Vrms (BMA) and 480 Vrms (SMA), with test voltage up to 1000 Vrms. 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 0.8–1.1 N·m.Materials and plating: center contacts are beryllium copper with 3 µin gold plating over 100 µin nickel-phosphorus underplating. Bodies are brass with gold plating; insulators are PTFE. Rated for −65 °C to +165 °C, this adapter offers 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.
