GPS external LNA enable signal
The module contains an internal LNA for the GPS antenna.
The user can though decide to use an external LNA: this option is selected by means of a
software command, which puts the internal LNA in a low gain mode and provides an
additional signal to enable the external LNA. The interface can provide a bias for the
external LNA, and the user can choose whether to enable it by this signal or to leave it
always enabled, by means of a jumper on PL202, as shown in the picture below.
