SMA R/P Plug (Male) to SMA Jack (Female) Adapter, DC-18GHz VSWR 1.2

SMA Reverse‑Polarity Plug (RP Male) to SMA Jack (Female) | Straight Adapter | Screw‑Lock | Brass Body

The ROSNOL AD‑A5A25A/111-11 is a straight RF adapter designed for 50‑ohm applications, covering DC to 18 GHz with VSWR ≤ 1.20 (return loss ≥ 20.83 dB). It specifies 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 interface ensures ≥ 500 mating cycles, axial captivation ≥ 27 N, radial captivation ≥ 3 N·cm, and recommended torque of 0.8–1.1 N·m. 

Constructed with a brass body and coupling nut, both finished with gold plating (3 micro‑inch) over non‑magnetic nickel‑phosphorus underplating (80 micro‑inch), this adapter includes brass center contacts with the same plating stack, PTFE insulator, and silicone rubber gasket. The multi‑layer plating enhances corrosion resistance and ensures stable RF performance across the operating 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.
