We have designed LoRa repeater board based on RAK3172 Module. We are planning to use external antenna based on SMA connector and the RF signal has been routed to this connector. RAK recommends to use a module without IPEX connector in this application (Mentioned in pin description and caution notes). We have used RAK3172-T-8-SM-I module in our sensor modules based on IPEX connector so can we use RAK3172-T-8-SM-NI which is without IPEX.?
Thank you for the quick response. We will use the module without IPEX Connector as IPEX antenna wont be sufficient for our requirement. Kindly check whether layout is fine or not. We will ask Fab house to strictly maintain 50ohm impedance.
