Description
SMA Female Panel Connector | Stub Terminal | Solder Attachment
The ROSNOL SMA2GTB50-1550A/91 is a high-performance SMA Female Panel Connector designed for RF systems operating up to 18 GHz. It features a solder cup terminal, solder attachment, and 2-hole flange mount with 12.22mm (.481 inch) spacing. With 50Ω impedance and screw-lock coupling, it ensures stable signal transmission and VSWR ≤ 1.30 (≥ 17.7 dB return loss). The connector supports up to 200W at 2 GHz and includes PTFE insulation for high reliability. Materials include gold-plated beryllium copper for the center contact and gold-plated brass for the body.Mechanical captivation is rated at axial ≥ 27 N and radial ≥ 3 Ncm, with recommended torque between 0.8 to 1.1 Nm. It complies with MIL-STD standards for vibration, shock, corrosion, and moisture resistance, and supports ≥ 500 mating cycles.
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 environmental safety and global regulatory alignment. Customization services for plating, materials, and mechanical design are available upon request.
