N Plug (Male) to SMA Jack (Female) | Straight Adapter | Screw-Lock | Brass Body
The ROSNOL AD-N1A25A/133-H3 is a precision RF adapter designed to connect N plug (male) to SMA jack (female), supporting broadband signal transmission from DC to 11 GHz. With a 50 Ω impedance, VSWR ≤ 1.20, and low insertion loss (≤ 0.03 × √F), this adapter ensures excellent signal integrity and minimal reflection in RF and microwave systems. The screw-on coupling interface on both sides provides secure mechanical engagement with ≥ 500 mating cycles and stable electrical performance.
The SMA side features a phosphor bronze center contact with gold plating, while the N side utilizes a brass center contact with gold plating, both over non-magnetic nickel-phosphorus underplating. The brass body with nickel plating offers reliable mechanical strength and corrosion resistance, while PTFE insulation ensures consistent dielectric properties. This balanced material configuration provides cost efficiency with stable RF performance for general-purpose applications.
This adapter is widely used in RF communication systems, antenna interfaces, test and measurement equipment, telecommunications infrastructure, and industrial RF integration. ROSNOL’s precision-engineered RF adapters deliver reliable performance across demanding environments, providing a cost-effective alternative to leading global brands. All ROSNOL RF components are manufactured in ISO 9001-certified facilities and comply with RoHS and REACH standards.
