SMA Reverse‑Polarity Plug (RP Male) to SMA Jack (Female) | Straight Adapter | Screw‑Lock | Stainless Steel Body
The ROSNOL AD-A5A25A/9XX‑9X is a straight RF adapter for 50‑ohm systems, operating from DC to 18 GHz with VSWR ≤ 1.20 (return loss ≥ 20.83 dB). It offers insertion loss ≤ 0.05 × √F (GHz) dB, insulation resistance ≥ 5 GΩ, center contact resistance ≤ 3 mΩ, and outer contact resistance ≤ 2 mΩ. Electrical ratings include 1000 V rms test voltage, 480 V rms working voltage, and power handling up to 200 W at 2 GHz. The screw‑lock coupling ensures secure engagement with ≥ 500 mating cycles, center contact captivation axial ≥ 27 N and radial ≥ 3 N·cm, coupling test torque ≤ 1.7 N·m, and recommended torque of 0.8–1.1 N·m.
This adapter features a stainless steel body with passivation, PTFE insulator, and beryllium copper center contacts plated with 3 micro‑inch gold over 80 micro‑inch non‑magnetic nickel‑phosphorus underplating. The coupling nut is stainless steel, and the gasket is silicone rubber, ensuring corrosion resistance and durability across a wide temperature range.
ROSNOL’s precision‑engineered RF adapters deliver reliable performance at competitive pricing, making them a strong alternative to products from leading European and American brands. All ROSNOL RF components are manufactured in ISO 9001‑certified facilities and fully comply with RoHS and REACH regulations. Customization services for materials, plating, and mechanical design are available to support specialized interconnect requirements.
