HN Plug (Male) to 7/16 Jack (Female) Adapter, DC-4GHz VSWR1.3

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

The ROSNOL AD-HN1D25A/133-H3 is a precision-engineered RF adapter designed for high-performance interconnects in demanding microwave systems. This straight adaptor operates across DC to 4 GHz with a 50 Ω impedance, ensuring minimal signal degradation. It delivers a VSWR of ≤1.3 and insertion loss of ≤0.05 × √F (GHz) dB, supporting excellent return loss performance. The adapter features a screw-lock coupling mechanism for secure connections and guarantees mechanical durability with ≥500 mating cycles. RF leakage is rated at ≥128 dB up to 1 GHz, and recommended coupling torque ranges from 0.7 Nm to 1.1 Nm on the HN side and up to 24.97 Nm on the 7/16 side, ensuring robust engagement under operational stress.

Constructed from premium materials, the center contacts are made of phosphor bronze and brass, plated with 3 µinch gold over an 80 µinch non-magnetic nickel-phosphorus underlayer for superior conductivity and corrosion resistance. The body components are precision-machined brass with nickel plating, while PTFE insulators provide excellent dielectric stability. A silicone rubber gasket enhances environmental sealing, and the coupling nut is nickel-plated brass for long-term reliability. The adapter withstands temperatures from -65°C to +165°C, ensuring consistent performance in harsh conditions.

ROSNOL’s RF adapters deliver exceptional quality and cost efficiency, making them a reliable alternative to leading European and American brands. All products are manufactured in ISO 9001-certified facilities and fully comply with RoHS and REACH regulations. Customization services for materials, plating, and mechanical design are available to meet specialized application requirements.
