Description
SMA Jack (Female) to SMA Jack (Female) to SMA Jack (Female) T-Adapter | Screw-Lock | Brass Body
The ROSNOL ADT‑A2A2A25A/91‑91‑91 is a compact SMA T‑adapter featuring three SMA Jack (Female) ports designed for stable RF performance from DC to 12.4 GHz. With 50‑ohm impedance, high insulation resistance, and a 1000 V rms test voltage rating, it supports reliable low‑loss signal distribution across multi‑port RF paths. The adapter ensures mechanical stability with screw‑lock coupling, a minimum of 500 mating cycles, and 27 N center‑contact captivation.The adapter uses beryllium copper center contacts with gold plating over a non‑magnetic nickel‑phosphorus underplating to ensure excellent conductivity and corrosion resistance. Its brass body with gold plating enhances durability, while PTFE insulators maintain stable dielectric performance. These material characteristics make the ADT‑A2A2A25A/91‑91‑91 suitable for RF test setups, signal routing networks, and systems requiring dependable multi‑port 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.
