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

SMA Jack (Female) to SMA Reverse‑Polarity Jack (Female) | Straight Adapter | Screw‑Lock | Stainless Steel Body

The ROSNOL AD‑A2A75B/9X-9X is a straight RF adapter designed for 50 ohm systems, operating from DC to 18 GHz with VSWR ≤ 1.20 (return loss ≥ 20.83 dB). It features low insertion loss defined as ≤ 0.05 × √F (GHz) dB, insulation resistance ≥ 5 GΩ, center contact resistance ≤ 3 mΩ, and outer contact resistance ≤ 2 mΩ. The adapter withstands a test voltage of 1000 V rms, supports a working voltage of 480 V rms, and offers power handling up to 200 W at 2 GHz. The screw‑lock coupling provides secure engagement with ≥ 500 mating cycles, center contact captivation of axial ≥ 27 N and radial ≥ 3 N·cm, a coupling test torque ≤ 1.7 N·m, and recommended torque of 0.8–1.1 N·m.

Constructed with a stainless steel body (passivated) and PTFE insulator, the adapter employs a beryllium copper center contact with gold plating (3 micro‑inch) over a non‑magnetic nickel‑phosphorus underplating (80 micro‑inch). This plating stack enhances corrosion resistance and electrical stability across the operating band. The robust material selection and finish support long service life and stable performance over typical RF temperature ranges.

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.
