GPS

[iremd]

Hello;
We want to use the  GPS peripheral of nRF9160. Qorvo QM14501SR LNA is used in your evaluation board. QM14501SR is expensive for our project. Can we use LNA without band pass filter instead?

Hi,

there are plenty of LNA's that can be used, but when the LTE radio is operating, the RF signal can intermodulate in the GPS LNA input stage and create unwanted harmonics, so the recommendation is to use an LNA with an integrated filter, or by adding a filter to the input of the LNA.

Best regards,
Kaja
