Description
SMA Jack (Female) Panel Connector | Screw-lock | Brass Body
The ROSNOL SMA2GTA50-1570A/91 is an SMA Jack (Female) panel connector engineered for RF and microwave applications from DC to 18 GHz with a characteristic impedance of 50 Ω. This model incorporates a 2-hole flange mount with a hole spacing of 12.22 mm (0.481 inch) and a stub solder terminal, enabling secure panel installation in compact RF systems. Electrical characteristics include VSWR ≤ 1.20 (Return Loss ≥ 20.83 dB), insertion loss ≤ 0.04 × √F (GHz) dB, insulation resistance ≥ 5 GΩ, and a working voltage of 480 V rms.The connector body is fabricated from brass with gold plating over a non-magnetic nickel-phosphorus underplating to ensure mechanical durability and stable grounding. A beryllium copper center contact with gold plating and a PTFE insulator provide stable impedance control and low loss at high frequencies. The standardized 2-hole flange geometry supports consistent mounting accuracy.
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 precision-manufactured in ISO 9001-certified facilities, and are fully RoHS and REACH compliant, ensuring global environmental and safety standards. Customization services for plating, materials, and mechanical design are available upon request.
