Description
TNC Jack (Female) to TNC Jack (Female) Adapter | Straight Design | Screw-Lock | Brass Body
The ROSNOL AD-T2T25A/H4-H4 is a straight TNC jack-to-jack adapter specified for DC to 11 GHz operation at 50 Ω. It achieves VSWR ≤ 1.25 (≥19.08 dB return loss) with insertion loss ≤ 0.05√F (GHz) dB. Electrical parameters include insulation resistance ≤ 5 mΩ, center contact resistance ≤ 1.5 mΩ, outer contact resistance ≤ 1 mΩ, test voltage 1500 V rms, working voltage 500 V rms, and power handling ≤ 80 W @ 2 GHz. The screw-lock coupling delivers secure engagement with ≥500 mating cycles, axial captivation ≥15 N, and a recommended torque of 0.46–0.69 Nm.Piece parts comprise phosphor bronze center contacts with gold plating (3 µinch) over a non-magnetic nickel‑phosphorus underplating (80 µinch), a Brass Copper-Tin-Zinc Alloy body, and PTFE insulators. This construction provides corrosion resistance and reliable thermal stability from −65°C to +155°C.
ROSNOL’s precision-engineered RF adapters deliver reliable performance across a wide range of RF and microwave systems. Designed to meet the stringent demands of high-frequency signal transmission, ROSNOL adapters offer a cost-effective 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, ensuring global environmental and safety standards. Customization services for materials, plating, and mechanical design are available to support specialized interconnect requirements.
