https://devzone.nordicsemi.com/f/nordic-q-a/62804/rf-lte-designHello, I&#39;m designing the electronic of the nRF9160. We use the ANT PIN (61) for frequencies in the range [700MHz; 2200MHz]. I&#39;m wondering to add a band filter on the line (like on the picture) between the ANT pin and the coaxial connector?
