RF Antenna

The LGA DevKit supports three antenna interfaces. The two SMA connectors "MAIN" and
"DRX" can used for radio transmission. The GNSS interface is supported by an U.FL connector
named "GPS".

All antenna interfaces have additional ESD protection implemented.

Figure 8:

S11 MAIN antenna module RF pad and S21 MAIN antenna RF loss

The LGA DevKit package includes a broad band high efficiency PCB antenna that can be used
with the DevKit for all radio band combinations.
