SMA Pulg (Male) to SMA Pulg (Male) Adapter, DC-18GHz VSWR 1.20

SMA Plug (Male) to SMA Plug (Male) Adapter | Straight Design | Screw-Lock | Beryllium Copper Body

The ROSNOL AD-A1A15A/999-999 is a precision 50-ohm straight adapter designed for DC to 18 GHz operation, delivering VSWR ≤ 1.20 (≥ 20.83 dB return loss) and insertion loss ≤ 0.03 × √F (GHz) dB. It ensures 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 capability up to 200 W at 2 GHz. Screw-lock coupling provides secure engagement, with mechanical endurance of ≥500 mating cycles and recommended torque of 0.8–1.1 Nm.

Piece-part construction includes beryllium copper center contacts and bodies finished with 3 microinch gold plating over a 100 microinch non-magnetic nickel-phosphorus underplating for optimal conductivity and longevity. PTFE insulators ensure stable dielectric performance, while silicone rubber gaskets enhance sealing for environmental protection. The design supports reliable service across −55°C to +155°C.

ROSNOL’s precision-engineered RF adapters deliver consistent broadband performance at competitive pricing, making them an effective alternative to leading European and American brands. All ROSNOL RF components are produced in ISO 9001-certified facilities and fully comply with RoHS and REACH regulations. Customization services for materials, plating, and mechanical design are available to accommodate specialized interconnect requirements.
