Image of Amphenol's QMA Series Quick-Locking In-Series and Between-Series AdaptersAmphenol RF's QMA adapters are offered with 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 up to ten times faster than the similar SMA interface. There is no additional tooling required and once the QMA adapters are mated, and they can be rotated 360° to improve the flexibility of the installation.

Designed with the same internal construction as the SMA series, the QMA adapters provide low-loss RF performance up to 18 GHz. The high power handling capability makes these adapters ideal for base stations, 5G wireless infrastructure, and a wide range of test and measurement equipment.
