QMA Adapters

Amphenol RF offers a variety of QMA adapters with both in-series and between series options available. These quick-locking adapters feature an innovative snap-on coupling mechanism that allows them to be installed into a system ten times faster than the similar SMA interface. There is no requirement for wrench clearance, which dramatically reduces the pitch. Once QMA adapters are mated, they can be rotated 360° to improve the flexibility of the installation.
