Description
SMA Male Connector with Stub Terminal | Stainless Steel Body
The SMA1GTA50-1525A/1XX is a high-performance SMA male connector featuring a stub solder terminal and 2-hole flange mount. Its screw-lock coupling mechanism supports over 500 mating cycles, with mechanical captivation ensuring secure axial and radial retention.Operating from DC to 18 GHz, this connector maintains a maximum VSWR of 1.30 (≥17.7 dB return loss) and supports up to 200 W power handling at 2 GHz. Low insertion loss (≤0.05 × √F GHz dB) ensures stable signal transmission across high-frequency applications.
The center contact is made of brass with 3 µinch gold plating over 80 µinch non-magnetic nickel-phosphorus underplating. The body and coupling nut are passivated stainless steel, while the insulator is PTFE and the gasket is silicone rubber, providing excellent durability and sealing.
