Description
SMA Jack to BNC Jack RF Adaptor | 4 Hole Panel Mount | Brass Body
The ROSNOL AD-A2B25A-PF/93-93 is a panel-mount RF adaptor featuring a jack-to-jack configuration with SMA (female) and BNC (female) interfaces. Designed for frequencies from DC to 4 GHz, it offers 50 Ω impedance, VSWR ≤ 1.20 (≥ 20.83 dB), and insertion loss ≤ 0.1 × √F (GHz) dB. The coupling mechanisms include a screw-lock for the SMA side and a bayonet-lock for the BNC side, ensuring secure mating. Operating temperature ranges from -65°C to +165°C, with RoHS compliance for environmental safety.The adaptor’s center contacts are made of beryllium copper with gold plating over nickel underplating. Both SMA and BNC bodies are constructed from nickel-plated brass, and the insulators are made of PTFE for stable dielectric performance. The unit is available in single or bulk packaging.
ROSNOL’s precision-engineered RF connectors offer a competitive alternative to products from leading manufacturers in Europe, the USA, and other global markets. All Rosnol RF components are precision-manufactured in ISO 9001-certified facilities, and are fully RoHS and REACH compliant, ensuring environmental safety and global regulatory alignment. Customization services for plating, materials, and mechanical design are available upon request.
