Key Specifications
Description
SMB Quick Plug (Male) to SMA Jack (Female) | Straight Adapter | Quick-Lock & Screw-Lock | Brass Body
The ROSNOL AD-SQ1A25A/911-91 is a high-quality RF adapter for DC to 4 GHz with 50 Ω impedance. It offers VSWR ≤ 1.35 and insertion loss ≤ 0.05√F (GHz) dB, ensuring low reflection and excellent return loss. Insulation resistance is ≥1 GΩ, and the adapter supports ≥500 mating cycles on both sides. Coupling mechanisms include quick-lock for SMB and screw-lock for SMA, with center contact captivation ≥10 N for secure engagement.
Center contacts are beryllium copper with 3 microinch gold plating over an 80 microinch nickel-phosphorus underplating. Bodies and coupling nuts are brass with corrosion-resistant finish, and insulators are PTFE. Recommended torque for the SMA side is 0.8–1.1 Nm. The operating temperature range spans −65°C to +165°C, providing durability under demanding conditions.
ROSNOL’s precision-engineered RF adapters deliver consistent performance and represent a cost-effective alternative to leading European and American brands. All components are manufactured in ISO 9001-certified facilities and comply with RoHS and REACH standards. Customization services for materials, plating, and mechanical design are available to support specialized interconnect needs.
