This is the IPX cable group. In this group you will find a variety of cables with SMA Male and SMA Female, as well as their RP SMA counterparts. The other end is of course, IPX. You will find extensions of 10mm and 20mm lengths and some that come with 90° connections. The coax cable is RG316 and the connectors and build quality are very good.
To help and avoid confusion, here is a chart that shows the different configurations of the SMA and RP SMA connectors.
