QMA connectors are available with 50 impedance. The frequency range extend 18GHz,
depending on the connector and cable type, however most of the QMA connectors are Return Loss
optimised for frequencies up to 6GHz.
The QMA interface is based on the SMA dimension, but instead of a threaded coupling mechanism,
a new snap-lcok mechanism used.
The QMA interface has a very similar performance to the SMA, but in addition it offers an easier, faster
and safer coupling operation, helping the customers to save significantly time during production of their
But QMA is not intermateable with SMA.
