Description This is 15CM RP-SMA Female to IPEX4 Connector Cable 11mm RG0.81. Cable specifications typically include the conductor’s impedance (e.g., 50 ohms to 75 ohms), which is important for maintaining signal integrity in RF applications. Additionally, the cable diameter and type (e.g., flexible, semi-rigid) play a role in its suitability for various applications. RP-SMA Female Connector: RP-SMA (Reverse Polarity SMA) is a variation of the SMA (SubMiniature version A) connector. The “RP” indicates a reverse gender configuration, meaning that the traditional roles of male and female connectors are switched. IPEX4 Connector: IPEX4 is a variant of the IPEX (IPX or U.FL) connector. IPEX connectors are miniature coaxial connectors used for connecting antennas to wireless devices like Wi-Fi cards, Bluetooth modules, and GPS receivers. Connector Length and Cable Length
