3.11 RF Antenna Interface

MC509 module provides an RF ANT PAD for connecting an external antenna. Through the MAIN_ANT pad, the antenna interface is routed to the coaxial connector on the DTE (Impedance 50).The external antenna is connected to the module through the coaxial connector.

A matching location for the antenna must be reserved at the antenna port.
