N Jack (Female) to QMA Jack (Female) Adapter, DC-5.6GHz VSWR1.15

N Jack (Female) to QMA Jack (Female) | Straight Adapter | Low PIM | Snap-Lock & Quick-Lock | Brass Body

The ROSNOL AD-N2QA25A/H4-H4-LP is a low PIM straight RF adapter designed for high-performance interconnection between N jack female and QMA jack female interfaces. It operates from DC to 5.6 GHz with 50-ohm impedance, VSWR ≤ 1.15, and insertion loss ≤ 0.05√F (GHz) dB. Electrical performance includes insulation resistance ≥ 5 MΩ, test voltage 1000 V rms, working voltage 480 V rms, RF leakage ≥ 95 dB up to 2 GHz, intermodulation ≤ -130 dBc at 2 × 20 W, 1800 MHz, and PIM level equal to or better than -154 dBc. The adapter features snap-lock coupling on the N side and quick-lock on the QMA side, ensuring axial captivation ≥ 28 N and durability for at least 500 mating cycles on the N side and 200 cycles on the QMA side. Recommended torque for the N side is 0.7–1.1 Nm, with a maximum coupling torque of 1.7 Nm.

Material construction ensures superior performance: both center contacts are phosphor bronze with gold plating over a non-magnetic nickel-phosphorus underlayer, and bodies are brass with copper-tin-zinc alloy finish. PTFE insulators provide excellent dielectric properties. This adapter withstands temperatures from -40°C to +85°C and offers excellent corrosion resistance for demanding RF environments.

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.
