HUBER SUHNER QMA User Manual
SERIES QMA, SUBMINIATURE CONNECTORS
DESCRIPTION
HUBER+SUHNER QMA coaxial connectors are available with 50 8 impedance. The frequency range extends to 18 GHz, depending on the connector and
cable type, however most of the QMA connectors are
ReturnLossoptimisedforfrequenciesupto6GHz.The
interface is based on the SMA dimension, but, instead
of a threaded coupling mechanism, a new snap-lock
mechanism is 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 systems.
The packaging density of QMA is increased compared
to SMA connectors thanks to the fact that no torque
spanner is required to fasten the coupling nut.
QMA is not intermateable with SMA.

FEATURES OF QMA CONNECTORS
QMA
> Cycle time improvement for making RF
connections (10 times faster to mount
than threaded connectors)
> No torque required
> Higher packaging density
> Free-rotating connection when mated
> Eliminates loosening problems associated
with threaded connectors
> Same performance as SMA up to 6 GHz
