SSMA Plug (Male) to SMA Jack (Female) | Straight Adapter | Screw-Lock | Brass Body
The ROSNOL AD‑SA1A25A/911‑91 is a compact SSMA Plug (Male) to SMA Jack (Female) adapter engineered for stable RF performance from DC to 18 GHz. With 50‑ohm impedance, ≤1.20 VSWR, high insulation resistance, and test voltages of 750 V rms (SSMA side) and 1000 V rms (SMA side), it supports reliable low‑loss transmission for high‑frequency applications. Both interfaces use a screw‑lock mechanism, offer at least 500 mating cycles, and feature 22 N center‑contact captivation for secure mechanical engagement.
The adapter uses beryllium copper center contacts with gold plating over a non‑magnetic nickel‑phosphorus underplating to ensure excellent conductivity and corrosion resistance. Brass bodies with gold plating provide durability, while PTFE insulators maintain stable dielectric properties across wide temperature ranges. A silicone rubber gasket enhances environmental resilience. These materials make the AD‑SA1A25A/911‑91 suitable for compact RF modules, microwave communication systems, and applications requiring reliable SSMA‑to‑SMA connectivity.
ROSNOL’s precision‑engineered solutions offer a competitive alternative to products from leading manufacturers in Europe, the USA, and other global markets. All ROSNOL components are manufactured in ISO 9001‑certified facilities and fully comply with RoHS and REACH regulations, ensuring environmental safety and global regulatory alignment. Customization services are available to meet specialized RF and microwave application requirements.
