RPSMA
RPSMA stands for Reverse Polarity SMA. It is a variation of the standard SMA (SubMiniature version A) connector used for radio frequency (RF) applications. The key difference lies in the pin and socket arrangement. In a standard SMA connector, the male connector has a central pin and the female connector has a central socket. In an RPSMA connector, this is reversed. The male RPSMA connector has a central socket, and the female RPSMA connector has a central pin.
This reversal of polarity is a deliberate design choice primarily to prevent accidental interconnections between standard
RPSMA connectors maintain the same overall dimensions and electrical characteristics as standard SMA connectors, meaning they
