SMA Plug (Male) Straight Connector 4 Hole Flange, 6.35mm (.250 inch) DC-18GHz VSWR1.30

SMA Plug (Male) | Solder attachment | 4-Hole Flange Mount | Brass Body |

The SMA1GFA50-1630B/111 is an SMA plug (male) RF connector engineered for reliable solder attachment and 4-hole flange mounting. It features a precise hole spacing of 6.35mm (.250 inch), facilitating standardized panel integration. The secure screw-lock coupling mechanism ensures consistent and robust connectivity in critical RF systems.

This connector is optimized for a wide range of radio frequency applications, performing effectively from DC to 18 GHz. It exhibits an excellent Voltage Standing Wave Ratio (VSWR) of $\le 1.30$, corresponding to a return loss of 17.7 dB, which is vital for maintaining signal integrity and minimizing power reflections across its operational bandwidth.

Crafted from high-quality materials, the center contact, body, and coupling nut are all made of brass. The center contact is gold-plated with a 3-pinch thickness and an 80-pinch non-magnetic nickel-phosphorus underplating. The body and coupling nut also feature gold plating over non-magnetic nickel-phosphorus underplating, ensuring excellent conductivity and corrosion resistance. The insulator is made of PTFE for optimal electrical isolation.
