Question

Both seem identical. For an application using nrf9151, is there a preferred unit? How could we select one over the other?

Answer 1

Hi,

The difference between the 2 are as follows:

M20047 the SAW filter is after the LNA

M20057 the SAW filter is before the LNA

The M20057 is better if there are other antennas close to the GNSS on  the PCB
