SMA Jack (Female) to TNC Jack (Female) Adapter | 4‑Hole Flange Mount | Brass Body
The ROSNOL AD-A2T25A-PF/93-93 is an SMA jack (female) to TNC jack (female) 4‑hole flange‑mount adapter engineered for reliable broadband operation from DC to 11 GHz. With 50 Ω impedance, VSWR ≤ 1.20, insertion loss ≤ 0.04 × √F(GHz), and insulation resistance ≥ 5 GΩ, the adapter ensures low‑loss conversion between SMA and TNC interfaces. Mechanical performance is supported by screw‑lock coupling on both sides, ≥ 500 mating cycles, and axial captivation ≥ 27 N, ensuring stable engagement in RF equipment.
The SMA and TNC sections utilize beryllium‑copper centre contacts with gold plating over a non‑magnetic nickel–phosphorus underlayer for excellent conductivity. Brass bodies with nickel plating provide mechanical strength, while PTFE insulators maintain dielectric stability across the full operating range. This adapter is well suited for RF test benches, broadband communications, measurement analyzers, and mixed‑interface instrumentation requiring SMA–TNC interconnectivity.
ROSNOL RF adapters are produced under ISO 9001‑certified processes and are fully compliant with RoHS and REACH environmental standards. Delivering high performance at competitive prices, ROSNOL products provide a dependable alternative to major international brands. Customization services—including materials, plating, and mechanical design options—are available to meet diverse technical requirements.
