Last Updated: 2026-02-11
The ROSNOL AD-A2PCN25A-PF/91‑94 is a high‑precision SMA jack (female) to Precision N jack (female) 4‑hole panel flange adapter designed for reliable performance across broadband RF and microwave systems. Engineered with a 50‑ohm impedance and supporting DC–18 GHz operation, this adapter ensures stable signal integrity with VSWR ≤ 1.2 and excellent return loss performance. The adapter offers low insertion loss (≤ 0.04 × √F(GHz) dB), high insulation resistance (≥ 5 GΩ), robust RF leakage suppression (≥ 90 dB up to 1 GHz), and secure screw‑lock coupling on both SMA and N sides for stable mating. Mechanical durability is supported by a minimum of 500 mating cycles, strong center‑contact captivation (≥ 28 N), and recommended torque ranges of 0.80–1.10 Nm (SMA) and 0.70–1.10 Nm (N). Its 4‑hole flange configuration enables rigid panel mounting for stable integration in system chassis and test platforms.
Constructed with premium materials, the adapter features beryllium‑copper center contacts with 3 µin gold plating over non‑magnetic nickel‑phosphorus underplating to ensure superior conductivity and long‑term corrosion resistance. The brass body provides structural strength, with gold-plated or copper‑tin‑zinc finishes depending on connector side, while PTFE insulators maintain excellent dielectric stability across the operating frequency range. A silicone‑rubber gasket enhances environmental sealing. This construction makes the AD-A2PCN25A-PF/91‑94 well‑suited for RF laboratory instrumentation, communication infrastructure, radar modules, embedded RF subsystems, and precision panel‑mounted interconnect assemblies requiring stable, low‑loss transitions between SMA and Precision N connectors.
All ROSNOL RF/microwave components, including the AD-A2PCN25A-PF/91‑94, are engineered and manufactured under ISO 9001‑certified quality systems to ensure consistent reliability. The product is fully RoHS and REACH compliant, meeting global environmental and safety regulations for worldwide deployment. ROSNOL continues to deliver high‑performance RF solutions tailored to the needs of modern microwave, wireless, and high‑frequency industries.
