3.8.1.1
Cellular Bands Antenna Connector
J31 covers two cellular bands, 800 MHz and 1900 MHz, as well as the GPS band, 1575 MHz, for passive aGPS.
3.8.1.2
GPS Antenna Connector
J30 is a GPS connector that provides the RF connection to the GPS receiver, as well as a user-defined DC voltage for an active
GPS antenna, which may be required in some configurations to increase sensitivity.
The DC voltage is provided by the user on the GPS_ANT_PWR pin on any of the three interconnects, and is routed to J30 via
an RF choke to decouple it from the RF signal.
