Amphenol RF (Danbury, CT) has announced an expansion of its QMA adapter product series. New quick-locking adapters are now available in both in-series and between-series configurations with N-Type, SMA and TNC options.

The new QMA adapters feature the company's snap-on coupling mechanism on one or both sides, as relevant. The adapters are intended for use in base stations, 5G wireless applications and test and measurement equipment.

Amphenol RF says the QMA adapters offer reliable low loss performance up to 18 GHz with high power handling. The adapters are designed with brass bodies that are either gold or white bronze plated, depending on the specific configuration. Multiple configurations are available to support a wide range of application needs and improve the capabilities of existing systems.

A snap-on mating mechanism allows these adapters to be installed into a system ten times faster than a similar SMA interface, claims the manufacturer. There are no requirements for wrench clearance, which dramatically reduces the pitch and, once the QMA adapters are mated, they can be rotated at 360° to improve the flexibility of installations, adds Amphenol RF.

The new QMA adapters join an extensive product series which includes connectors and pre-configured cable assemblies. Custom solutions are available upon request. Learn more at
