Last Updated: 2026-02-11
The ROSNOL AD‑A2PCN25A‑PF/9X‑HX is a high‑accuracy SMA jack (female) to Precision N jack (female) adapter engineered for 50‑ohm, DC–18 GHz RF systems requiring stable electrical performance. The adapter ensures VSWR ≤ 1.2, insertion loss ≤ 0.04 × √F(GHz) dB, insulation resistance ≥ 5 GΩ, test voltage 1000 V rms, working voltage 480 V rms, and RF leakage ≥ 90 dB up to 1 GHz. Screw‑lock coupling mechanisms provide secure mating for vibration‑exposed installations, while the 4‑hole mounting flange supports rigid panel integration. Mechanical endurance includes ≥ 500 mating cycles, axial center‑contact retention ≥ 28 N, and recommended torque ranges of 0.80–1.10 Nm (SMA) and 0.70–1.10 Nm (Precision N).
The AD‑A2PCN25A‑PF/9X‑HX utilizes high‑grade materials to maintain RF stability and dimensional reliability. The Precision N center contact is constructed from phosphor bronze with 3 µin gold plating over an 80 µin nickel‑phosphorus underplate, while the SMA center contact uses beryllium‑copper with identical plating specifications. Both sides employ passivated stainless‑steel bodies for corrosion resistance and structural integrity. PTFE dielectric elements contribute to stable impedance control, aided by a silicone‑rubber gasket for environmental protection. These structural advantages support industries ranging from RF laboratory testing and wireless communication development to microwave system integration and precision panel‑mount assemblies.
All ROSNOL RF components—including the AD‑A2PCN25A‑PF/9X‑HX—are produced under ISO 9001‑certified quality systems to ensure dependable manufacturing standards. Fully compliant with RoHS and REACH regulations, this adapter meets global environmental and safety requirements for international RF and microwave applications.
