QMA connector

The QMA series of connectors from VidaRF offers excellent low loss performance from DC-6GHz. A QMA connector is essentially an SMA with a quick disconnect connection. The QMA’s popularity stems from the fact that it offers high power handling capabilities similar to the SMA – but in a package that provides much flexibility. No threaded coupler means no requirements for wrench clearance. 360-degree rotation after mating increases installation options.

Finally, the snap on coupling makes instillation of QMA connectors many times faster than SMA’s. QMA connectors can be ordered from VidaRF as plugs or jacks, as cable connectors or adapters.
