1.5 Antenna interface
The antenna interface is a 50 Ω coaxial connector. Matching networks are not included on the
module and should be placed in the host application if the antenna is not 50 Ω. The HIROSE
U.FL compatible connector is located on the TOP side of the board.
NOTE! The used connector has gold plated contacts - whereas a standard HIROSE U-FL has
silver plated contacts.
If silver - gold joints are not allowed in your product, use gold plated cable-connector to mate to
this device.
