Special feature of RP connectors

RP connectors—meaning Reverse Polarity—have reversed contact gender. For example, an RP-SMA Male connector actually has a Female pin. To avoid confusion, we name RP connectors according to their external form, hence the terms “Plug” and “Jack”.

In manufacturer documentation, RP-SMA may also be written as “R-SMA” or “SMA Reverse”.
