Description
SMA Plug (Male) to N Jack (Female) | 4-Hole Flange Panel Adapter | Screw-lock | Brass Body
The ROSNOL AD-A1N25A-PF/H11-H3 is a precision SMA-to-N panel adapter designed for secure flange mounting in RF and microwave systems. It supports DC to 11 GHz with 50 Ω impedance, VSWR ≤ 1.15 (≥ 23.1 dB return loss), and insertion loss ≤ 0.04√f (GHz) dB. Electrical integrity includes insulation resistance ≥ 5 GΩ, RF leakage ≥ 100 dB up to 1 GHz, and power handling up to 200 W at 2 GHz. Mechanical features include screw-lock coupling, ≥ 500 mating cycles, and recommended torque of 0.8–1.1 Nm (SMA) and 0.7–1.1 Nm (N).The SMA and N contacts are phosphor bronze with 3 μinch gold plating over 80 μinch non-magnetic nickel-phosphorus underplating. SMA body and coupling nut are brass with gold plating, while N body uses brass with copper-tin-zinc alloy finish. PTFE insulators ensure excellent dielectric performance, complemented by silicone rubber gaskets for environmental sealing.
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.
