7/16 Plug (Male) to N Jack (Female) Low Pin Adapter, DC-7.5GHz VSWR 1.2

7/16 Plug (Male) to N Jack (Female) Adapter | Straight Design | Screw-Lock | Brass Body

The ROSNOL LPAD-D1N25A/H44-H4 is a low PIM 50-ohm straight adapter optimized for DC to 7.5 GHz, achieving VSWR ≤ 1.20 (≥ 20 dB return loss) and insertion loss ≤ 0.05 × √F (GHz) dB. It offers robust electrical characteristics including insulation resistance ≤ 5 mΩ, center contact resistance ≤ 1 mΩ (N side) and ≤ 0.4 mΩ (7/16 side), and outer contact resistance ≤ 0.25 mΩ (N side) and ≤ 1.5 mΩ (7/16 side). RF leakage is rated at ≥128 dB up to 1 GHz, and PIM level exceeds −155 dBc. The adapter supports working voltage up to 500 Vrms and power handling ≥ 20 W. Both ends utilize screw-lock coupling with axial captivation ≥ 200 N and mechanical endurance of ≥ 500 mating cycles; recommended torque is 0.7–1.1 Nm for N side and 25–30 Nm for 7/16 side.

Materials and plating are engineered for reliability: phosphor bronze center contacts with gold plating over a non-magnetic nickel-phosphorus underplating ensure superior conductivity and wear resistance. Bodies and coupling nuts are brass copper-tin-zinc alloy, while PTFE insulators provide stable dielectric properties. The adapter operates reliably across a −65°C to +155°C temperature range.

ROSNOL’s RF adapters combine precision engineering with cost efficiency, offering a dependable alternative to major global brands. Manufactured under ISO 9001-certified processes and fully compliant with RoHS and REACH, ROSNOL products guarantee quality and environmental safety. Customization options for materials, plating, and mechanical design are available to support unique application needs.
