Description
SMA Plug (Male) to SMA Plug (Male) Adapter | Straight Design | Screw-Lock | Brass Body
The ROSNOL AD-A1A15A/133-133 is a high-performance 50-ohm straight adapter optimized for DC to 18 GHz, achieving VSWR ≤ 1.20 (≥ 20.83 dB return loss) and insertion loss ≤ 0.05 × √F (GHz) dB. It offers insulation resistance ≥ 5 GΩ, center contact resistance ≤ 3 mΩ, and outer contact resistance ≤ 2 mΩ. RF leakage is rated at ≥100 dB up to 1 GHz, with power handling up to 200 W at 2 GHz. Both ends utilize screw-lock coupling for secure engagement and mechanical endurance of ≥500 mating cycles; recommended torque is 0.8–1.1 Nm.Materials and plating are engineered for durability: brass center contacts with gold plating over a non-magnetic nickel-phosphorus underplating ensure superior conductivity and wear resistance. Bodies and coupling nuts are brass with nickel plating, while PTFE insulators and silicone rubber gaskets provide environmental sealing. The adapter operates reliably across a −65°C to +155°C temperature range.
ROSNOL’s RF adapters combine precision engineering with cost efficiency, offering a dependable alternative to major global brands. Manufactured under ISO 9001-certified processes and fully compliant with RoHS and REACH, ROSNOL products guarantee quality and environmental safety. Customization options for materials, plating, and mechanical design are available to support unique application needs.
