Nice to meet you. I am Defond company engineer. I am responsible for develop GNSS platform in IOT product. I would like to use M20057-1 GNSS module. SIM7070 IC GNSS pin will connect to M20057-1 RFO. There are two external matching components for AT1 and AT1. How to determine these external mattching two components value?
Another question, does it need to make a matching circuit in RFO pin?
Thanks in advance.
