Overview
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 which 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, they can be
rotated 360° to improve the flexibility of the installation.
Designed with the same internal construction as the
SMA series, 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.
