I used the nRF9151 Feather for a proof-of-concept hardware design. While it worked fine, it’s too large for the required form factor. I copied the RF front end from the nRF9151 schematic, but I’m not getting any GPS fixes. I’m using AGNSS, and the CNx is the same outdoor, indoors, and even switching antennas. To me, that suggests that the LNA isn’t functional. I tested this on all 5 of my prototypes, and did not get a signal. Re-touched the LNA pins, no help. The only difference between the two designs is that Im running the nRF9151 and the LNA on 1.8V, not 3.3V. Could that cause the issue? Thank you in advance for your help.
