Hubner+Suhner adaptors are used within measuring applications with QMA interfaces. These versatile adaptors support the calibration with Hubne+Suhner open standard interfaces, incorporating the same electrical length and the same return loss behaviour of all this series of adaptors the swapping method can be utilised.

HUBER+SUHNER QMA

The interface is based on the SMA dimensions, 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, resulting in significant time saving during the production of systems. The packaging density of QMA is increased compared to SMA connectors as no torque spanner is required to fasten the coupling nut.
