Reverse-polarity SMA (RP-SMA or RPSMA) is a variation of the SMA connector specification which reverses the gender of the interface. This non-standard type SMA connector finds common applications in WiFi and WLAN systems and is the most popular reverse polarity RF connector. The reverse polarity characteristic is achieved with a reverse mating interface in which the RP-SMA connector male houses the female receptacle while the RP-SMA connector female/jack houses the center pin.
