RP-SMA to ...

RP-SMA is designed for a diverse range of RF applications and is suitable for communications DC to 18GHz.

Identical to SMA design, but have a reversed gender. Gender naming is made in reference to the plug or socket's body rather than conventionally by the pin itself. This means that a RP-SMA Male connector will have a female receptacle - i.e. the pin's gender is reversed, hence reversed polarity.
