Description
SMA Connector | End Launch Thru‑Hole PCB | Screw‑Lock | Gold‑Plated Brass Body
The ROSNOL SMA2MA50-2243A/91 is a commercial‑grade SMA Jack (Female) designed for thru‑hole PCB end‑launch applications, supporting 50 Ω operation from DC to 18 GHz with VSWR ≤1.25. Its screw‑lock coupling ensures reliable high‑frequency engagement, with ≥500 mating cycles, axial captivation ≥20 N, and recommended torque of 0.8–1.1 Nm.Material construction includes a gold‑plated brass body, gold‑plated beryllium‑copper center contact, PTFE dielectric, and brass fastening hardware for secure PCB mounting. Typical engineering applications include RF front‑end boards, distribution panels, modular microwave assemblies, and measurement system interfaces.
ROSNOL delivers high‑quality RF interconnect solutions at competitive pricing, manufactured in ISO 9001‑certified facilities and fully compliant with RoHS and REACH standards. Designed as a cost‑effective alternative to leading European and American brands, our components offer reliable performance and long‑term stability. We also provide flexible customization options for materials, plating, and mechanical design.
