Side-mount SMT female connector. Good little connector mainly used for RF but fine general signal use - the edge-mount type here are very handy for use on 1.6mm thick PCBs.
Note that WiFi for inscrutable reasons uses male sockets and female plugs rather than the standard female sockets and male plugs, don't buy the wrong lead(!)

I think they do that so any Tom, Dick or Harry don’t go and hook up a higher gain antenna to whatever wireless device it might be. TNC uses reverse thread (pain in the a$$ when that happens by accident).Note that WiFi for inscrutable reasons uses male sockets and female plugs rather than the standard female sockets and male plugs, don't buy the wrong lead(!)
The pins in females, socket in males is also done to allow a designer of equipment the opportunity to prevent incorrect connection of something that could accidentally cause damage (TX to RX) for example. Especially on smaller devices.
Yes, it must be SMA-Female. It is widely used in a radio-transmitting devices with coaxial cables up to tens of GHz.
Wifi devices use similar reverse polarity connector (RP-SMA), but this on the photo is straight SMA connector.

We used these and SMB (no threads) for digital video and instrument IO. It's a small 50 Ohm connection since older 50 Ohm connections are huge and not suited for SMB PCBs. But these are not new, ie 60 years old. Compatibility between SMA and 3.5mm can be a PITA, and connectors can be "ruined" by using the wrong one.
