Mini-QMA Connector
The Mini-QMA is a quick-locking SMA (QMA) replacement that was designed with panel mount and printed circuit board (PCB) applications specifically in mind; the length of the Mini-QMA being the shortest of any QMA connector on the market to date. This miniaturization, in addition to its snap-on coupling mechanism and electronic performance equivalent to SMA up to 18 GHz, make the Mini-QMA an excellent choice for applications in which space is limited but performance is required.
