Hi,

The LTE pin and GPS pin should be connected to its appropriate matching network and with a 50 ohm RF switch between the matching network and antenna.

Hi guys,

Have you been through with this design? If I understand well, I still have to connect the antenna signal to both LTE and GPS antenna pins, but with a switched matching network right?

Thanks,

Marc

Hi,

This would require a matching network for each band that you're going to use the antenna with. A switch that reroute the signal to the appropriate matching network would also be required. More info regarding matching network can be found in our documentation on antenna tuning here.
