nRF9160 GPS Antenna Termination if not in use

[sheddanl]

I'm just redesigning a circuit using the nRF9160 and wanted a second opinion on this.

I am no longer using the GPS antenna on this chip, and I want to make sure this antenna is still terminated properly. I can see in the nRF9160 datasheet (page 367), that the GPS antenna pin is DC grounded However, I'm not sure if that means it is grounded while it is not in use or not. Do I need to add anything on the PCB to properly terminate the antenna, even though it will not be used.

Thanks very much!

Just leave it open. There's an internal switch in the module and when the GPS Is not in use, the GPS ANT pin is disconnected.
