Description
SMA Jack (Female) | High-Frequency RF Connector | Solder Attachment | 2-Hole Flange Mount | Brass Body
The ROSNOL SMA2GTC50-1450A/91 is a precision-engineered SMA RF connector designed for high-frequency applications requiring secure solder attachment and flange mounting. It operates from DC to 18 GHz with 50 Ω impedance, VSWR ≤ 1.30 (≥ 17.7 dB return loss), and insertion loss ≤ 0.05√f (GHz) dB. Electrical performance includes insulation resistance ≥ 5 GΩ, test voltage 1000 V rms, and working voltage 480 V rms. Power handling capability reaches 200 W at 2 GHz. Hole Spacing: 12.22 mm (.481 inch). Mechanical integrity is ensured with screw-lock coupling, ≥ 500 mating cycles, and captivated semicircular terminal for enhanced durability.The center contact is beryllium copper with gold plating (3 μinch) over nickel-phosphorus underplating (80 μinch), while the body is brass with gold plating for superior corrosion resistance. PTFE insulation ensures excellent dielectric properties, and the connector withstands temperatures from -65°C to +165°C.
ROSNOL’s high-frequency RF connectors deliver a cost-effective alternative to leading global brands. Manufactured in ISO 9001-certified facilities, all components meet RoHS and REACH compliance standards. Customization options for plating, materials, and mechanical design are available to support specialized interconnect requirements.
