Description
SMA Termination Load Jack (Female) | DC to 12 GHz | 50 Ω | 2 W
The ROSNOL T-A25-12G2WA/91 is a high-performance SMA termination load designed for broadband RF applications up to 12 GHz. It provides a nominal impedance of 50 Ω and maintains a VSWR of ≤ 1.20 (Return Loss ≥ 20.83 dB), ensuring stable impedance matching and minimal signal reflection. Rated for 2 W average power at 25°C, this termination supports demanding RF environments and features a screw-lock coupling mechanism for secure and repeatable connections. The unit operates reliably across a temperature range of -55°C to +155°C.Constructed from premium materials, the center contact is beryllium copper with gold plating over a non-magnetic nickel-phosphorus underlayer, ensuring excellent electrical conductivity and corrosion resistance. The body and coupling nut are brass with gold plating for enhanced mechanical strength. A PTFE insulator provides stable dielectric properties, and a silicone rubber gasket ensures environmental sealing. This termination is widely used in RF laboratories, telecom infrastructure, and automated test systems requiring robust mid-power terminations.
ROSNOL RF components are produced under ISO 9001-certified quality management systems and comply fully with RoHS and REACH regulations. Offering superior RF performance and mechanical reliability at competitive pricing, ROSNOL terminations serve as cost-effective alternatives to major global brands. Customization options for plating, materials, and mechanical design are available to support unique application requirements.
