Description
SSMB Plug (Male) to SMA Jack (Female) | Straight Adapter | Snap-Lock & Screw-Lock | Brass Body
The ROSNOL AD-SB1A25A/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 snap-lock for SSMB 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 exceptional electrical performance, mechanical reliability, and cost efficiency. Designed to meet stringent RF industry standards, they provide superior durability and consistent signal integrity even in demanding environments. All components are manufactured in ISO 9001-certified facilities and comply with RoHS and REACH standards. ROSNOL offers customization for materials, plating, and mechanical design, ensuring tailored solutions for specialized applications and competitive alternatives to leading global brands.
