SMA Plug (Male) to SMA Jack (Female) Bulkhead Adapter, DC-18GHz VSWR 1.20

SMA Plug (Male) to SMA Jack (Female) | Bulkhead with Sealing | Screw-Lock | Beryllium Copper Body

The ROSNOL AD-A1A25A-BH/999-99 is a sealed bulkhead SMA plug-to-jack adapter optimized for DC to 18 GHz with 50 Ω impedance. It offers VSWR ≤ 1.20 (Return Loss ≥ 20.8 dB), insertion loss ≤ 0.03 × √f (GHz), insulation resistance ≥ 5 GΩ, test voltage 1000 V rms, working voltage 480 V rms, and power handling up to 200 W at 2 GHz. A screw-lock coupling ensures axial center-contact captivation ≥ 27 N, radial captivation ≥ 3 N·cm, mechanical durability ≥ 500 mating cycles, and recommended torque of 0.8–1.1 Nm.

Piece parts and plating: center contact, body, and coupling nut in beryllium copper with gold plating over non‑magnetic nickel‑phosphorus underplating; PTFE insulator; silicone rubber gasket; fastening nut and washer in brass with gold over nickel‑phosphorus. The configuration supports a broad operating temperature from −65 °C to +165 °C while maintaining corrosion resistance via the Ni‑P underplating system.

ROSNOL’s precision-engineered RF adapters provide dependable performance for RF and microwave systems. Built under ISO 9001‑certified processes and fully compliant with RoHS and REACH, ROSNOL delivers high quality at competitive pricing as an effective alternative to established European and American brands. Comprehensive customization services are available to tailor materials, plating, and mechanical design to your requirements.
