PCB vendor have finished our M20057-1 board. Now we can tune M20057-1 module antenna matching.
In our experience, we understand how to tune passive antenna. But we have no experience to tune your active antenna. Do you have any simple guideline (or step) for your GNSS module matching tuning? Can I use network analyzer to tune M20057-1 GNSS antenna matching tune?
my step(I am not sure):
1. Apply 3v to M20057-1 Vcc and then network analyzer connect to RFO capacitor.
2. measure RFO return loss.
3. What components value(in AT1 and AT2) can be use when I tune the matching?
Thanks in advance.
