TE Connectivity’ next generation high performance RF products QMA (Snap On SMA) connectors series offers the same high quality and performance currently found in the standard TE Connectivity SMA series but does not require the coupling nut torque. By integrating a snap on feature to the design, denser packaging can be achieved, and the overall applied cost is dramatically reduced. The QMA connector series is excellent for communications as well as industrial applications. The QMA connector offering is designed for 100 mating cycles, operates through 6 GHz, and is completely intermateable with competitive QMA offerings. This new QMA product is not intermateable with standard SMA interfaces.

QMA connectors are available in a broad range of standard configurations, including PCB and panel mount, flexible and semi-rigid cable, and adapters. Other options can be reviewed as well, including additional cable sizes, PCB surface mounting, and tape and reel packaging. The QMA connector series is a cost effective solution for the challenging demands of today’s commercial marketplace.
