GPS Antenna Circuit

Balamurugan

Hi,

we are progress of designing custom board using nRF9160.

By reading nRF documentation, my understanding is GPS circuit in Dev kit is unstable/nonperforming.

Could you please share new/updated GPS antenna section schematic.

Also please suggest smd small size ceramic antenna for Cellular-RF.

Thanks.

    Hi,

     

    This could possibly be used. As mentioned you should make sure you are able to replicate the recommended mounting in your end product, and that it supports the bands you plan on using.

    I notice that it has two matching configurations, one that supports 700-800 MHz, and one that supports 820-960 MHz. If you plan on supporting both in your product you then need to implement an antenna tuning circuit, two RF switches that can switch to different antenna matching circuits depending on the band/frequency operating at.

     

    Best regards,

    Andreas
