N Jack (Female) to 7/16 Jack (Female) 4-Hole Panel Adapter, DC-0.5GHz VSWR1.15

N Jack (Female) to 7/16 Jack (Female) | 4-Hole Panel Adapter | Low PIM | Screw-Lock | Brass Body

The ROSNOL AD-N2D25A-PF/H4-H4 is a low PIM 4-hole panel RF adapter designed for high-performance interconnection between N jack female and 7/16 jack female interfaces. It operates from DC to 500 MHz with 50-ohm impedance, VSWR ≤ 1.15, and PIM level better than -153 dBc (2×43 dBm). Electrical performance includes insulation resistance ≥ 5 GΩ, working voltage 500 V rms, and power handling up to 1000 W at 1 GHz and 700 W at 2 GHz. The adapter features screw-lock coupling on both sides, axial captivation ≥ 200 N, and supports at least 500 mating cycles. Recommended torque is 0.7–1.1 Nm for the N side and 25–30 Nm for the 7/16 side.

Material construction ensures superior performance: both center contacts are phosphor bronze with gold plating over nickel-phosphorus underlayer, and bodies are brass with copper-tin-zinc alloy finish. PTFE insulators provide excellent dielectric properties, and silicone rubber gaskets enhance environmental sealing. The adapter is IP68-rated when mated and operates reliably from -65°C to +165°C.

ROSNOL’s precision-engineered RF adapters deliver high quality and dependable performance at competitive pricing, making them an ideal alternative to leading European and American brands. All ROSNOL components are manufactured in ISO 9001-certified facilities and comply with RoHS and REACH regulations. Customization services for materials, plating, and mechanical design are available to meet specialized interconnect requirements.
