QMA Subminiature RF Connectors
RoHS
Compliant
TM
Winchester manufactures the QMA series to utilize a quick connect mating system that
does not require special tooling for mating/unmating. The QMA connector system was
designed around the internal construction of an SMA, which allows the QMA to have
excellent electrical/power characteristics.
Winchester’s QMA is fully interchangeable with any other
QMA connector and is equal in performance.
The mechanical design of the QMA centers around a snap-on mating versus a
threaded coupling like the SMA. This allows denser packaging and reduced installation
labor. The QMA has an added benefit of being able to rotate 360° after mating, allowing
flexibility during installation with no change in performance.
Winchester’s QMA connectors have excellent PIM performance up to -120dBc. The
QMA Plugs can be enhanced with an internal grounding feature, which will increase the
PIM performance up to -135 dBc. We can also offer an internal seal for weatherproof
applications.
Product Benefits:
Ø Snap-on interface for easy installation.
Ø When mated, the connectors can rotate 360 degrees.
Ø Electrical performance similar to an SMA up to 6 GHz.
Ø Excellent PIM performance to -120dBc (enhanced version to -135 dBc).
Ø Optional weatherproofing seal.
