SMA Jack (Female) PCB Bulkhead End Launch Connector, DC-18GHz VSWR1.25

SMA Jack (Female) PCB Connector | End‑Launch / Through‑Hole | Screw‑lock | Brass Body

The ROSNOL SMA2MA50-1725A/91 is a commercial‑grade SMA Jack (Female) PCB connector designed for end‑launch and through‑hole solder attachment. It supports 50 Ω operation from DC to 18 GHz with VSWR ≤ 1.25 (return loss ≥ 19.08 dB), insertion loss ≤ 0.04 × √F (GHz) dB, insulation resistance ≥ 5 GΩ, center contact resistance ≤ 3 mΩ, outer contact resistance ≤ 2 mΩ, RF leakage ≥ 100 dB up to 1 GHz, working voltage 480 V rms (test voltage 1000 V rms), and power handling up to 200 W @ 2 GHz and 100 W @ 10 GHz (at 20 °C, sea level, VSWR 1.0). As with all board‑edge launches, achievable VSWR is strongly influenced by the PCB launch footprint, ground via fence, and housing clearances.Mechanical characteristics include screw‑lock coupling with ≥ 500 mating cycles, center‑contact captivation ≥ 20 N (axial), recommended coupling torque 0.80–1.10 N·m (maximum 1.70 N·m). Board mounting style is end‑launch / through‑hole. 

Material and plating: body—brass with gold plating over non‑magnetic nickel‑phosphorus underplating; center contact—beryllium copper with gold plating over non‑magnetic nickel‑phosphorus underplating; insulator—PTFE; fastening nut and washer—brass with gold plating over nickel‑phosphorus. This construction ensures reliable solderability, stable grounding, and repeatable microwave performance in commercial environments.

ROSNOL’s precision‑engineered RF connectors offer a competitive alternative to products from leading manufacturers in Europe, the USA, and other global markets. All Rosnol RF components are manufactured in ISO 9001‑certified facilities and are fully RoHS and REACH compliant, ensuring global environmental and safety standards. Customization services for materials, plating, and mechanical design are available upon request.
